INTEGRATION OF MACHINERY
（From ELECTRICAL AND MACHINERY INDUSTRY）ABSTRACT
Machinery was the modern science and technology development inevitable result, this article has summarized the integration of machinery technology basic outline and the development background .Summarized the domestic and foreign integration of machinery technology present situation, has analyzed the integration of machinery technology trend of development.
Key word：integration of machinery ，technology，present situation ，product t，echnique of manufacture ，trend of development
0. Introduction modern science and technology unceasing development, impelled different discipline intersecting enormously with the seepage, has caused the project domain technological revolution and the transformation .In mechanical engineering domain, because the microelectronic technology and the computer technology rapid development and forms to the mechanical industry seepage the integration of machinery, caused the mechanical industry the technical structure, the product organization, the function and the constitution, the production method and the management system has had the huge change, caused the industrial production to enter into "the integration of machinery" by "the machinery electrification" for the characteristic development phase.
1. Integration of machinery outline integration of machinery is refers in the organization new owner function, the power function, in the information processing function and the control function introduces the electronic technology, unifies the system the mechanism and the computerization design and the software which constitutes always to call. The integration of machinery development also has become one to have until now own system new discipline, not only develops along with the science and technology, but also entrusts with the new content .But its basic characteristic may summarize is: The integration of machinery is embarks from the system viewpoint, synthesis community technologies and so on utilization mechanical technology, microelectronic technology, automatic control technology, computer technology, information technology, sensing observation and control technology, electric power electronic technology, connection technology, information conversion technology as well as software programming technology, according to the system function goal and the optimized organization goal, reasonable disposition and the layout various functions unit, in multi-purpose, high grade, redundant reliable, in the low energy consumption significance realize the specific function value, and causes the overall system optimization the systems engineering technology .From this produces functional system, then becomes an integration of machinery systematic or the integration of machinery product. Therefore, "integration of machinery" covering "technology" and "product" two aspects .Only is, the integration of machinery technology is based on the above community technology organic fusion one kind of comprehensive technology, but is not mechanical technical, the microelectronic technology as well as other new technical simple combination, pieces together .This is the integration of machinery and the machinery adds the machinery electrification which the electricity forms in the concept basic difference .The mechanical engineering technology has the merely technical to develop the machinery electrification, still was the traditional machinery, its main function still was replaces with the enlargement physical strength .But after develops the integration of machinery, micro electron installment besides may substitute for certain mechanical parts the original function, but also can entrust with many new functions, like the automatic detection, the automatic reduction information, demonstrate the record, the automatic control and the control automatic diagnosis and the protection automatically and so on .Not only namely the integration of machinery product is human's hand and body extending, human's sense organ and the brains look, has the
intellectualized characteristic is the integration of machinery and the machinery electrification distinguishes in the function essence.
2. Integration of machinery development condition integration of machinery development may divide into 3 stages roughly.20th century 60's before for the first stage, this stage is called the initial stage .In this time, the people determination not on own initiative uses the electronic technology the preliminary achievement to consummate the mechanical product the performance .Specially in Second World War period, the war has stimulated the mechanical product and the electronic technology union, these mechanical and electrical union military technology, postwar transfers civilly, to postwar economical restoration positive function .Developed and the development at that time generally speaking also is at the spontaneous condition .Because at that time the electronic technology development not yet achieved certain level, mechanical technical and electronic technology union also not impossible widespread and thorough development, already developed the product was also unable to promote massively. The 20th century 70~80 ages for the second stage, may be called the vigorous development stage .This time, the computer technology, the control technology, the communication development, has laid the technology base for the integration of machinery development . Large-scale, ultra large scale integrated circuit and microcomputer swift and violent development, has provided the full material base for the integration of machinery development .This time characteristic is :①A mechatronics word first generally is accepted in Japan, probably obtains the quite widespread acknowledgment to 1980s last stages in the worldwide scale ;②The integration of machinery technology and the product obtained the enormous development ;③The various countries start to the integration of machinery technology and the product give the very big attention and the support. 1990s later periods, started the integration of machinery technology the new stage which makes great strides forward to the intellectualized direction, the integration of machinery enters the thorough development time .At the same time, optics, the communication and so on entered the integration of machinery, processes the technology also zhan to appear tiny in the integration of machinery the foot, appeared the light integration of machinery and the micro integration of machinery and so on the new branch; On the other hand to the integration of machinery system modeling design, the analysis and the integrated method, the integration of machinery discipline system and the
trend of development has all conducted the thorough research .At the same time, because the huge
progress which domains and so on artificial intelligence technology, neural network technology and optical fiber technology obtain, opened the development vast world for the integration of machinery technology .These research, will urge the integration of machinery further to establish the integrity the foundation and forms the integrity gradually the scientific system. Our country is only then starts from the beginning of 1980s in this aspect to study with the application .The State Council had been established the integration of machinery leading group and lists as "863 plans" this technology .When formulated "95" the plan and in 2010 developed the summary had considered fully on international the influence which and possibly brought from this about the integration of machinery technology development trend .Many universities, colleges and institutes, the development facility and some large and middle scale enterprises have done the massive work to this technical development and the application, does not yield certain result, but and so on the advanced countries compared with Japan still has the suitable disparity.
3. Integration of machinery trend of development integrations of machinery are the collection machinery, the electron, optics, the control, the computer, the information and so on the multi-disciplinary overlapping syntheses, its development and the progress rely on and promote the correlation technology development and the progress .Therefore, the integration of machinery main development direction is as follows:
3.1 Intellectualized intellectualizations are 21st century integration of machinery technological development important development directions .The artificial intelligence obtains day by day in the integration of machinery constructor's research takes, the robot and the numerical control engine bed intellectualization is the important application .Here said "the intellectualization" is to the machine behavior description, is in the control theory foundation, the absorption artificial intelligence, the operations research, the computer science, the fuzzy mathematics, the psychology, the physiology and the chaos dynamics and so on the new thought, the new method, simulate the human intelligence, enable it to have abilities and so on judgment inference, logical thinking, independent decision-making, obtains the higher control goal in order to .Indeed, enable the integration of machinery product to have with the human identical intelligence, is not impossible, also is nonessential .But, the high
performance, the high speed microprocessor enable the integration of machinery product to have preliminary intelligent or human's partial intelligences, then is completely possible and essential.
In the modern manufacture process, the information has become the control manufacture industry the determining factor, moreover is the most active actuation factor .Enhances the manufacture system information-handling capacity to become the modern manufacture science development a key point .As a result of the manufacture system information organization and structure multi-level, makes the information the gain, the integration and the fusion presents draws up the character, information measure multi-dimensional, as well as information organization's multi-level .In the manufacture information structural model, manufacture information uniform restraint, dissemination processing and magnanimous data aspects and so on manufacture knowledge library management, all also wait for further break through.
Each kind of artificial intelligence tool and the computation intelligence method promoted the manufacture intelligence development in the manufacture widespread application .A kind based on the biological evolution algorithm computation intelligent agent, in includes the
scheduling problem in the combination optimization solution area of technology, receives the more and more universal attention, hopefully completes the combination optimization question when the manufacture the solution speed and the solution precision aspect breaks through the question scale in pairs the restriction .The manufacture intelligence also displays in: The intelligent dispatch, the intelligent design, the intelligent processing, the robot study, the intelligent control, the intelligent craft plan, the intelligent diagnosis and so on are various
These question key breakthrough, may form the product innovation the basic research system. Between 2 modern mechanical engineering front science different science overlapping fusion will have the new science accumulation, the economical development and society's progress has had the new request and the expectation to the science and technology, thus will form the front science .The front science also has solved and between the solution scientific question border area .The front science has the obvious time domain, the domain and the dynamic characteristic .The project front science distinguished in the general basic science important characteristic is it has covered the key science and technology question which the project actual appeared.
Manufacture system is a complex large-scale system, for satisfies the manufacture system agility, the fast response and fast reorganization ability, must profit from the information science, the life sciences and the social sciences and so on the multi-disciplinary research results, the exploration manufacture system new architecture, the manufacture pattern and the manufacture system effective operational mechanism .Makes the system optimization the organizational structure and the good movement condition is makes the system modeling , the simulation and the optimized essential target .Not only the manufacture system new architecture to makes the enterprise the agility and may reorganize ability to the demand response ability to have the vital significance, moreover to made the enterprise first floor production equipment the flexibility and may dynamic reorganization ability set a higher request .The biological manufacture view more and more many is introduced the manufacture system, satisfies the manufacture system new request.
The study organizes and circulates method and technique of complicated system from the biological phenomenon, is a valid exit which will solve many hard nut to cracks that manufacturing industry face from now on currently .Imitating to living what manufacturing point is mimicry living creature organ of from the organization, from match more, from growth with from evolution etc. function structure and circulate mode of a kind of manufacturing system and manufacturing process.
The manufacturing drives in the mechanism under, continuously by one's own perfect raise on organizing structure and circulating mode and thus to adapt the process of[with] ability for the environment .For from descend but the last product proceed together a design and make a craft rules the auto of the distance born, produce system of dynamic state reorganization and product and manufacturing the system tend automatically excellent provided theories foundation and carry out a condition .Imitate to living a manufacturing to belong to manufacturing science and life science of\"the far good luck is miscellaneous to hand over\", it will produce to the manufacturing industry for 21 centuries huge of influence .

摘要
机电一体化是现代科学技术发展的必然结果,本文简述了机电一体化技术的基本概要和发展背景。综述了国内外机电一体化技术的现状，分析了机电一体化技术的发展趋势。
关键词
机电一体化技术现状产品制造技术发展趋势
1．绪论
现代科学技术的不断发展，极大地推动了不同学科的交叉与渗透，导致了工程领域的技术革命与改造。在机械工程领域，由于微电子技术和计算机技术的迅速发展及其向机械工业的渗透所形成的机电一体化，使机械工业的技术结构、产品机构、功能与构成、生产方式及管理体系发生了巨大变化，使工业生产由"机械电气化"迈入了"机电一体化"为特征的发展阶段。
2．机电一体化概要
机电一体化是指在机构得主功能、动力功能、信息处理功能和控制功能上引进电子技术，将机械装置与电子化设计及软件结合起来所构成的系统的总称。
机电一体化发展至今也已成为一门有着自身体系的新型学科，随着科学技术的不但发展，还将被赋予新的内容。但其基本特征可概括为：机电一体化是从系统的观点出发，综合运用机械技术、微电子技术、自动控制技术、计算机技术、信息技术、传感测控技术、电力电子技术、接口技术、信息变换技术以及软件编程技术等群体技术，根据系统功能目标和优化组织目标，合理配置与布局各功能单元，在多功能、高质量、高可靠性、低能耗的意义上实现特定功能价值，并使整个系统最优化的系统工程技术。由此而产生的功能系统，则成为一个机电一体化系统或机电一体化产品。
因此，"机电一体化"涵盖"技术"和"产品"两个方面。只是，机电一体化技术是基于上述群体技术有机融合的一种综合技术，而不是机械技术、微电子技术以及其它新技术的简单组合、拼凑。这是机电一体化与机械加电气所形成的机械电气化在概念上的根本区别。机械工程技术有纯技术发展到机械电气化，仍属传统机械，其主要功能依然是代替和放大的体力。但是发展到机电一体化后，其中的微电子装置除可取代某些机械部件的原有功能外，还能赋予许多新的功能，如自动检测、自动处理信息、自动显示记录、自动调节与控制自动诊断与保护等。即机电一体化产品不仅是人的手与肢体的延伸，还是人的感官与头脑的眼神，具有智能化的特征是机电一体化与机械电气化在功能上的本质区别。
3．机电一体化的发展状况
机电一体化的发展大体可以分为3个阶段。20世纪60年代以前为第一阶段，这一阶段称为初级阶段。在这一时期，人们自觉不自觉地利用电子技术的初步成果来完善机械产品的性能。特别是在第二次世界大战期间，战争刺激了机械产品与电子技术的结合，这些机电结合的军用技术，战后转为民用，对战后经济的恢复起了积极的作用。那时研制和开发从总体上看还处于自发状态。由于当时电子技术的发展尚未达到一定水平，机械技术与电子技术的结合还不可能广泛和深入发展，已经开发的产品也无法大量推广。
20世纪70~80年代为第二阶段，可称为蓬勃发展阶段。这一时期，计算机技术、控制技术、通信技术的发展，为机电一体化的发展奠定了技术基础。大规模、超大规模集成电路和微型计算机的迅猛发展，为机电一体化的发展提供了充分的物质基础。这个时期的特点是：①首先在日本被普遍接受，大约到20世纪80年代末期在世界范围内得到比较广泛的承认；②机电一体化技术和产品得到了极大发展；③各国均开始对机电一体化技术和产品给以很大的关注和支持。
化进入深入发展时期。一方面，光学、通信技术等进入了20世纪90年代后期，开始了机电一体化技术向智能化方向迈进的新阶段，机电一体机电一体化，微细加工技术也在机电一体化中崭露头脚，出现了光机电一体化和微机电一体化等新分支；另一方面对机电一体化系统的建模设计、分析和集成方法，机电一体化的学科体系和发展趋势都进行了深入研究。同时，由于人工智能技术、神经网络技术及光纤技术等领域取得的巨大进步，为机电一体化技术开辟了发展的广阔天地。这些研究，将促使机电一体化进一步建立完整的基础和逐渐形成完整的科学体系。
我国是从20世纪80年代初才开始在这方面研究和应用。国务院成立了机电一体化领导小组并将该技术列为"863计划"中。在制定"九五"规划和2010年发展纲要时充分考虑了国际上关于机电一体化技术的发展动向和由此可能带来的影响。许多大专院校、研究机构及一些大中型企业对这一技术的发展及应用做了大量的工作，不取得了一定成果，但与日本等先进国家相比仍有相当差距。4．机电一体化的发展趋势
机电一体化是集机械、电子、光学、控制、计算机、信息等多学科的交叉综合，它的发展和进步依赖并促进相关技术的发展和进步。因此，机电一体化的主要发展方向如下：
4.1智能化
智能化是21世纪机电一体化技术发展的一个重要发展方向。人工智能在机电一体化建设者的研究日益得到重视，机器人与数控机床的智能化就是重要应用。
这里所说的"智能化"是对机器行为的描述，是在控制理论的基础上，吸收人工智能、运筹学、计算机科学、模糊数学、心理学、生理学和混沌动力学等新思想、新方法，模拟人类智能，使它具有判断推理、逻辑思维、自主决策等能力，以求得到更高的控制目标。诚然，使机电一体化产品具有与人完全相同的智能，是不可能的，也是不必要的。但是，高性能、高速的微处理器使机电一体化产品赋有低级智能或人的部分智能，则是完全可能而又必要的。
在现代制造过程中，信息不仅已成为主宰制造产业的决定性因素，而且还是最活跃的驱动因素。提高制造系统的信息处理能力已成为现代制造科学发展的一个重点。由于制造系统信息组织和结构的多层次性，制造信息的获取、集成与融合呈现出立体性、信息度量的多维性、以及信息组织的多层次性。在制造信息的结构模型、制造信息的一致性约束、传播处理和海量数据的制造知识库管理等方面，都还有待进一步突破。
各种人工智能工具和计算智能方法在制造中的广泛应用促进了制造智能的发展。一类基于生物进化算法的计算智能工具，在包括调度问题在内的组合优化求解技术领域中，受到越来越普遍的关注，有望在制造中完成组合优化问题时的求解速度和求解精度方面双双突破问题规模的制约。制造智能还表现在：智能调度、智能设计、智能加工、机器人学、智能控制、智能工艺规划、智能诊断等多方面。
现代机械工程的前沿科学间的交叉融合将产生新的科学聚集，经济的发展和社会的进步对科学技术产生了新的要求和期望，从而形成前沿科学。前沿科学也就是已解决的和未解决的科学问题之间的界域。前沿科学具有明显的时域、领域和动态特性。工程前沿科学区别于一般基础科学的重要特征是它涵盖了工程实际中出现的关键科学技术问题。
制造系统是一个复杂的大系统，为满足制造系统敏捷性、快速响应和快速重组的能力，必须借鉴信息科学、生命科学和社会科学等多学科的研究成果，探索制造系统新的体系结构、制造模式和制造系统有效的运行机制。制造系统优化的组织结构和良好的运行状况是制造系统建模、仿真和优化的主要目标。制造系统新的体系结构不仅对制造企业的敏捷性和对需求的响应能力及可重组能力有重要意义，而且对制造企业底层生产设备的柔性和可动态重组能力提出了更高的要求。生物制造观越来越多地被引入制造系统，以满足制造系统新的要求。
21世纪将是生命科学的世纪，机械科学和生命科学的深度融合将产生全新概念的产品(如智能仿生结构)，开发出新工艺(如生长成形工艺)和开辟一系列的新产业，并为解决产品设计、制造过程和系统中一系列难题提供新的解决方法。这是一个极富创新和挑战的前沿领域。
从生命现象中学习组织与运行复杂系统的方法和技巧，是今后解决目前制造业所面临许多难题的一条有效出路。仿生制造指的是模仿生物器官的自组织、自愈合、自增长与自进化等功能结构和运行模式的一种制造系统与制造过程。
制造在机制的驱动下，在组织结构和运行模式上不断自我完善、从而提高对于环境适应能力的过程。为自下而上的产品并行设计、制造工艺规程的自动生成、生产系统的动态重组以及产品和制造系统的自动趋优提供了理论基础和实现条件。
制造属于制造科学和生命科学的"远缘杂交"，它将对21世纪的制造业产生巨大的影响。

工业设计原著选读 优秀的产品设计 第一个拨号电话1897年由卡罗耳Gantz 第一个拨号电话在1897年被自动电器公司引入，成立于1891年布朗强，一名勘萨斯州承担者。在1889年，相信铃声“中央交换”将转移来电给竞争对手，强发明了被拨号系统控制的自动交换机系统。这个系统在1892年第一次在拉波特完成史端乔系统中被安装。1897年，强的模型电话，然而模型扶轮拨条的位置没有类似于轮齿约170度,以及边缘拨阀瓣。电话，当然是被亚历山大格雷厄姆贝尔（1847—1922）在1876年发明的。第一个商业交换始建于1878（12个使用者），在1879年，多交换机系统由工程师勒罗伊B 菲尔曼发明,使电话取得商业成功,用户在1890年达到250000。 直到1894年，贝尔原批专利过期，贝尔电话公司在市场上有一个虚拟的垄断。他们已经成功侵权投诉反对至少600竞争者。该公司曾在1896年，刚刚在中央交易所推出了电源的“普通电池”制度。在那之前，一个人有手摇电话以提供足够的电力呼叫。一个连接可能仍然只能在给予该人的名义下提出要求达到一个电话接线员。这是强改变的原因。 强很快成为贝尔的强大竞争者。他在1901年引进了一个桌面拨号模型，这个模型在设计方面比贝尔的模型更加清晰。在1902年，他引进了一个带有磁盘拨号的墙面电话，这次与实际指孔，仍然只有170度左右在磁盘周围。到1905年，一个“长距离”手指孔已经被增加了。最后一个强的知名模型是在1907年。强的专利大概过期于1914年，之后他或他的公司再也没有听到过。直到1919年贝尔引进了拨号系统。当他们这样做，在拨号盘的周围手指孔被充分扩展了。 强发明的拨号系统直到1922年进入像纽约一样的大城市才成为主流。但是一旦作为规规范被确立，直到70年代它仍然是主要的电话技术。后按键式拨号在1963年被推出之后，强发明的最初的手指拨号系统作为“旋转的拨号系统”而知名。这是强怎样“让你的手指拨号”的。 埃姆斯椅LCW和DCW 1947 这些带有复合曲线座位，靠背和橡胶防震装置的成型胶合板椅是由查尔斯埃姆斯设计，在赫曼米勒家具公司生产的。 这个原始的概念是被查尔斯埃姆斯（1907—1978）和埃罗沙里宁（1910—1961）在1940年合作构想出来的。在1937年，埃姆斯成为克兰布鲁克学院实验设计部门的领头人，和沙里宁一起工作调查材料和家具。在这些努力下，埃姆斯发明了分成薄片和成型胶合板夹板，被称作埃姆斯夹板，在1941年收到了来自美国海军5000人的订单。查尔斯和他的妻子雷在他们威尼斯，钙的工作室及工厂和埃文斯产品公司的生产厂家一起生产了这批订单。 在1941年现代艺术博物馆，艾略特诺伊斯组织了一场比赛用以发现对现代生活富有想象力的设计师。奖项颁发给了埃姆斯和沙里宁他们的椅子和存储碎片，由包括埃德加考夫曼，大都会艺术博物馆的阿尔弗雷德，艾略特诺伊斯，马尔塞布鲁尔，弗兰克帕里什和建筑师爱德华达雷尔斯通的陪审团裁决。 这些椅子在1946年的现代艺术展览博物馆被展出，查尔斯埃姆斯设计的新的家具。当时，椅子只有三条腿，稳定性问题气馁了大规模生产。 早期的LCW（低木椅）和DWC（就餐木椅）设计有四条木腿在1946年第一次被埃文斯产品公司（埃姆斯的战时雇主）生产出来，被赫曼米勒家具公司分配。这些工具1946年被乔治纳尔逊为赫曼米勒购买，在1949年接手制造权。后来金属脚的愿景在1951年制作，包括LCW（低金属椅）和DWC（就餐金属椅）模型。配套的餐饮和咖啡桌也产生。这条线一直

液压传动 第十讲 制动器 力流体动力系统的优秀的特性之一是由电源产生，通过适当的控制和指导，并通过电线传输，就可以轻松转换到几乎任何类型的机械运动所需要用到的地方。使用一个合适的驱动装置，可以获得线性（直线）或者是旋转运动。驱动器是一种转换流体动力机械力和运动的装置。缸、马达和涡轮机是最常见的将流体动力系统应用于驱动设备的类型。这一章描述了各种类型的动作汽缸和他们的应用程序、不同类型的流体汽车和使用流体动力系统的涡轮机。 汽缸 制动汽缸是一种将流体动力转换成线性或直线、力和运动的装置。因为线性运动是沿着一条直线前后移动的往复运动。这种类型的制动器有时被称为一个往复、或线性、电动机。由ram或活塞组成的汽缸在一个圆柱孔内操作。制动汽缸可以安装，以便汽缸被固定在一个固定的结构，ram或活塞被连接到该机制来操作，或者是活塞和ram可能被固定到固定结构，汽缸附加到机械装置来操作。制动汽缸气动和液压系统的设计和操作是类似的。一些变化的ram和活塞式制动汽缸的内容将在后面的段落中描述。 冲压式缸 术语ram和活塞通常可以互换使用。然而，一个冲压式缸通常被认为是一个截面积活塞杆超过一半的截面积活动元件。在大多数这种类型的制动汽缸中，杆和活动元件各占一半。这种类型的活动元件经常被称为柱塞。冲压式缸主要是用来推动而不是拉。一些应用程序需要ram的一部分在平坦的外部来推动或升降单位操作。其他应用程序需要一些机械装置的附件，如一个U型夹或有眼螺栓。冲压式缸的设计在很多其他方面不同，以满足不同应用程序的要求。 单作用千斤顶 单作用千斤顶（如图：10-1）试用力只在一个方向。流体定向的汽缸取代ram 和他外部的弹性元件，将物体举起放在上面。

附件1：外文资料翻译译文 冲压模具设计 对于汽车行业与电子行业，各种各样的板料零件都是有各种不同的成型工艺所生产出来的，这些均可以列入一般种类“板料成形”的范畴。板料成形（也称为冲压或压力成形）经常在厂区面积非常大的公司中进行。 如果自己没有去这些大公司访问，没有站在巨大的机器旁，没有感受到地面的震颤，没有看巨大型的机器人的手臂吧零件从一个机器移动到另一个机器，那么厂区的范围与价值真是难以想象的。当然，一盘录像带或一部电视专题片不能反映出汽车冲压流水线的宏大规模。站在这样的流水线旁观看的另一个因素是观看大量的汽车板类零件被进行不同类型的板料成形加工。落料是简单的剪切完成的，然后进行不同类型的加工，诸如：弯曲、拉深、拉延、切断、剪切等，每一种情况均要求特殊的、专门的模具。 而且还有大量后续的加工工艺，在每一种情况下，均可以通过诸如拉深、拉延与弯曲等工艺不同的成形方法得到所希望的得到的形状。根据板料平面的各种各样的受应力状态的小板单元体所可以考虑到的变形情形描述三种成形，原理图1描述的是一个简单的从圆坯料拉深成一个圆柱水杯的成形过程。 图1 板料成形一个简单的水杯
拉深是从凸缘型坯料考虑的，即通过模具上冲头的向下作用使材料被水平拉深。一个凸缘板料上的单元体在半径方向上被限定，而板厚保持几乎不变。板料成形的原理如图2所示。 拉延通常是用来描述在板料平面上的两个互相垂直的方向被拉长的板料的单元体的变形原理的术语。拉延的一种特殊形式，可以在大多数成形加工中遇到，即平面张力拉延。在这种情况下，一个板料的单元体仅在一个方向上进行拉延，在拉长的方向上宽度没有发生变化，但是在厚度上有明确的变化，即变薄。 图2 板料成形原理 弯曲时当板料经过冲模，即冲头半径加工成形时所观察到的变形原理，因此在定向的方向上受到改变，这种变形式一个平面张力拉长与收缩的典型实例。 在一个压力机冲程中用于在一块板料上冲出一个或多个孔的一个完整的冲压模具可以归类即制造商标准化为一个单工序冲孔模具，如图3所示。

Interaction design Moggridge Bill Interaction design，Page 1-15 USA Art Press, 2008 Interaction design (IxD) is the study of devices with which a user can interact, in particular computer users. The practice typically centers on "embedding information technology into the ambient social complexities of the physical world."[1] It can also apply to other types of non-electronic products and services, and even organizations. Interaction design defines the behavior (the "interaction") of an artifact or system in response to its users. Malcolm McCullough has written, "As a consequence of pervasive computing, interaction design is poised to become one of the main liberal arts of the twenty-first century." Certain basic principles of cognitive psychology provide grounding for interaction design. These include mental models, mapping, interface metaphors, and affordances. Many of these are laid out in Donald Norman's influential book The Psychology of Everyday Things. As technologies are often overly complex for their intended target audience, interaction design aims to minimize the learning curve and to increase accuracy and efficiency of a task without diminishing usefulness. The objective is to reduce frustration and increase user productivity and satisfaction. Interaction design attempts to improve the usability and experience of the product, by first researching and understanding certain users' needs and then designing to meet and exceed them. (Figuring out who needs to use it, and how those people would like to use it.) Only by involving users who will use a product or system on a regular basis will designers be able to properly tailor and maximize usability. Involving real users, designers gain the ability to better understand user goals and experiences. (see also: User-centered design) There are also positive side effects which include enhanced system capability awareness and user ownership. It is important that the user be aware of system capabilities from an early stage so that expectations regarding functionality are both realistic and properly understood. Also, users who have been active participants in a product's development are more likely to feel a sense of ownership, thus increasing overall satisfa. Instructional design is a goal-oriented, user-centric approach to creating training and education software or written materials. Interaction design and instructional design both rely on cognitive psychology theories to focus on how users will interact with software. They both take an in-depth approach to analyzing the user's needs and goals. A needs analysis is often performed in both disciplines. Both, approach the design from the user's perspective. Both, involve gathering feedback from users, and making revisions until the product or service has been found to be effective. (Summative / formative evaluations) In many ways, instructional

段，即：20世纪50年代初到60年代初为起步阶段；60~70年代为专业化生产体系成长阶段；80~90年代为快速发展阶段。其中，液压工业于50年代初从机床行业生产仿苏的磨床、拉床、仿形车床等液压传动起步，液压元件由机床厂的液压车间生产，自产自用。进入60年代后，液压技术的应用从机床逐渐推广到农业机械和工程机械等领域，原来附属于主机厂的液压车间有的独立出来，成为液压件专业生产厂。到了60年代末、70年代初，随着生产机械化的发展，特别是在为第二汽车制造厂等提供高效、自动化设备的带动下，液压元件制造业出现了迅速发展的局面，一批中小企业也成为液压件专业制造厂。1968年中国液压元件年产量已接近20万件；1973年在机床、农机、工程机械等行业，生产液压件的专业厂已发展到100余家，年产量超过100万件，一个独立的液压件制造业已初步形成。这时，液压件产品已从仿苏产品发展为引进技术与自行设计相结合的产品，压力向中、高压发展，并开发了电液伺服阀及系统，液压应用领域进一步扩大。气动工业的起步比液压稍晚几年，到1967年开始建立气动元件专业厂，气动元件才作为商品生产和销售。含橡塑密封、机械密封和柔性石墨密封的密封件工业，50年代初从生产普通O型圈、油封等挤压橡塑密封和石棉密封制品起步，到60年代初，开始研制生产机械密封和柔性石墨密封等制品。70年代，在原燃化部、一机部、农机部所属系统内，一批专业生产厂相继成立，并正式形成行业，为密封件工业的发展成长奠定了基础。 进入80年代，在国家改革开放的方针指引下，随着机械工业的发展，基础件滞后于主机的矛盾日益突出，并引起各有关部门的重视。为此，原一机部于1982年组建了通用基础件工业局，将原有分散在机床、农业机械、工程机械等行业归口的液压、气动和密封件专业厂，统一划归通用基础件局管理，从而使该行业在规划、投资、引进技术和科研开发等方面得到基础件局的指导和支持。从此进入了快速发展期，先后引进了60余项国外先进技术，其中液压40余项、气动7项，经消化吸收和技术改造，现均已批量生产，并成为行业的主导产品。近年来，行业加大了技术改造力度，1991~1998年国家、地方和企业自筹资金总投入共约20多亿元，其中液压16亿多元。经过技术改造和技术攻关，一批主要企业技术水平进一步提高，工艺装备得到很大改善，为形成高起点、专业化、批量生产打下了良好基础。近几年，在国家多种所有制共同发展的方针指引下，不同所有制的中小企业迅猛崛起，呈现出

Injection Molding The basic concept of injection molding revolves around the ability of a thermoplastic material to be softened by heat and to harden when cooled .In most operations ,granular material (the plastic resin) is fed into one end of the cylinder (usually through a feeding device known as a hopper ),heated, and softened(plasticized or plasticized),forced out the other end of the cylinder, while it is still in the form of a melt, through a nozzle into a relatively cool mold held closed under pressure.Here,the melt cools and hardens until fully set-up. The mold is then opened, the piece ejected, and the sequence repeated. Thus, the significant elements of an injection molding machine become: 1) the way in which the melt is plasticized (softened) and forced into the mold (called the injection unit); 2) the system for opening the mold and closing it under pressure (called the clamping unit);3) the type of mold used;4) the machine controls. The part of an injection-molding machine, which converts a plastic material from a sold phase to homogeneous seni-liguid phase by raising its temperature .This unit maintains the material at a present temperature and force it through the injection unit nozzle into a mold .The plunger is a combination of the injection and plasticizing device in which a heating chamber is mounted between the plunger and mold.

DESIGN and ENVIRONMENT Product design is the principal part and kernel of industrial design. Product design gives uses pleasure. A good design can bring hope and create new lifestyle to human. In spscificity,products are only outcomes of factory such as mechanical and electrical products,costume and so on.In generality,anything,whatever it is tangibile or intangible,that can be provided for a market,can be weighed with value by customers, and can satisfy a need or desire,can be entiled as products. Innovative design has come into human life. It makes product looking brand-new and brings new aesthetic feeling and attraction that are different from traditional products. Enterprose tend to renovate idea of product design because of change of consumer's lifestyle , emphasis on individuation and self-expression,market competition and requirement of individuation of product. Product design includes factors of society ,economy, techology and leterae humaniores. Tasks of product design includes styling, color, face processing and selection of material and optimization of human-machine interface. Design is a kind of thinking of lifestyle.Product and design conception can guide human lifestyle . In reverse , lifestyle also manipulates orientation and development of product from thinking layer.

液压传动系统 作者：Hopmans, ArthurH. 摘要 液压传动是由液压泵、液压控制阀、液压执行元件和液压辅件组成的液压系统。液压泵把机械能转换成液体的压力能，液压控制阀和液压辅件控制液压介质的压力、流量和流动方向，将液压泵输出的压力能传给执行元件，执行元件将液体压力能转换为机械能，以完成要求的动作。 关键词：液压传动；气压传动；传动系统； 许多液压传动先前已经设计出允许操作者无限变化输出的变速器，或甚至逆转的传动装置的输出作为相对于输入。通常情况下，这已经通过使用一个旋转斜盘是要么由操作者手动或操作液压动机来改变通过旋转泵头部具有轴向移动的活塞流动的液压流体的。液压流体从泵头活塞的流动，依次转动的马达头通过激励相应的一组活塞在其中违背一固定凸轮的，因此，旋转安装在电动机头的输出轴。 通常情况下，在现有技术的变速器已被被设置有各种功能，例如齿轮减速，刹车设定装置等。不幸的是，这些功能通常是提供外部发送的和显著增加整个装置的体积和质量。申请人确定，这是很期望具有其中基本上所有的这些需要或希望的功能，可以在内部提供的发送，同时还产生一个非常有效的和非常有效的传输的综合传输。 特别是，这种类型的变速器上经常使用的设备，如“零转动半径”剪草机之类的其中一个潜在的危险情况面对操作者，旁观者和设备本身，如果设备我们允许继续被推进应的操作者释放控制，由于当操作者无意中从装置抛出或变得受伤。因此，“故障自动刹车”机制经常被设置为传输自动地返回到中立配置在这种情况下，使得该装置不会继续供电，如果控制被释放。 先前传输这种类型的一般依靠某种外部设备，比如其目的是为了在操作者控制轴返回到中立位置应操作者释放所述轴的反操作偏压弹簧。这种类型的外部设备，可以容易地由用户或篡改损坏。这种回归函数中性到传输本身的整合允许在外部零件的减少可被损坏或不适当取出并大大降低，以支持传输的各种功能所需的外部结构。 在这种类型的用于割草机的使用和类似的传输经常遇到的另一个问题是，操作时会略生涩或有弹性，因为操作者通常无法顺利地控制从一个速度到另一个的过渡，往往试图使突然变化。从这些生涩的操作震动有一种倾向，穿更重的机器和操作上也是如此。因此，理想的是抑制这种传输的输出，以防止这种不平稳的运动。 不仅是它是期望能够有一个返回到中立的功能，如desribed以上，但还希望为操作者有积极的感觉为中立位置时，不论操作者从空档移动到前进或从中立扭转。此功能在本文中称为积极中性功能，并且在一般情况下，该功能需要操作者在从发送到任何一个正向或反向方向的中立姿势变换扩展更多的能量或运动相比，量能量消耗或运动需从一个速度转移到另一个在一个特定的方向。与上面提到的其它特征，最好是需要提供此功能的结构的发送本身内掺入。

The mold designing and manufacturing The mold is the manufacturing industry important craft foundation, in our country, the mold manufacture belongs to the special purpose equipment manufacturing industry. China although very already starts to make the mold and the use mold, but long-term has not formed the industry. Straight stabs 0 centuries 80's later periods, the Chinese mold industry only then drives into the development speedway. Recent years, not only the state-owned mold enterprise had the very big development, the three investments enterprise, the villages and towns (individual) the mold enterprise's development also rapid quietly. Although the Chinese mold industrial development rapid, but compares with the demand, obviously falls short of demand, its main gap concentrates precisely to, large-scale, is complex, the long life mold domain. As a result of in aspect and so on mold precision, life, manufacture cycle and productivity, China and the international average horizontal and the developed country still had a bigger disparity, therefore, needed massively to import the mold every year . The Chinese mold industry must continue to sharpen the productivity, from now on will have emphatically to the profession internal structure adjustment and the state-of-art enhancement. The structure adjustment aspect, mainly is the enterprise structure to the specialized adjustment, the product structure to center the upscale mold development, to the import and export structure improvement, center the upscale automobile cover mold forming analysis and the structure improvement, the multi-purpose compound mold and the compound processing and the laser technology in the mold design manufacture application, the high-speed cutting, the super finishing and polished the technology, the information direction develops . The recent years, the mold profession structure adjustment and the organizational reform step enlarges, mainly displayed in, large-scale, precise, was complex, the long life, center the upscale mold and the mold standard letter development speed is higher than the common mold product; The plastic mold and the compression casting mold proportion increases; Specialized mold factory quantity and its productivity increase;

I was newly arrived at Apple, still learning the ways of business, when I was visited by a member of Apple's Industrial Design team. He showed me a foam mockup of a proposed product. "Wow," I said, "I want one! What is it?" That experience brought home the power of design: I was excited and enthusiastic even before I knew what it was. This type of visceral "wow" response requires creative designers. It is subjective, personal. Uh oh, this is not what engineers like to hear. If you can't put a number to it, it's not important. As a result, there is a trend to eliminate designers. Who needs them when we can simply test our way to success? The excitement of powerful, captivating design is defined as irrelevant. Worse, the nature of design is in danger. Don't believe me? Consider Google. In a well-publicized move, a senior designer at Google recently quit, stating that Google had no interest in or understanding of design. Google, it seems, relies primarily upon test results, not human skill or judgment. Want to know whether a design is effective? Try it out. Google can quickly submit samples to millions of people in well-controlled trials, pitting one design against another, selecting the winner based upon number of clicks, or sales, or whatever objective measure they wish. Which color of blue is best? Test. Item placement? Test. Web page layout? Test. This procedure is hardly unique to Google. https://www.360docs.net/doc/6012399631.html, has long followed this practice. Years ago I was proudly informed that they no longer have debates about which design is best: they simply test them and use the data to decide. And this, of course, is the approach used by the human-centered iterative design approach: prototype, test, revise. Is this the future of design? Certainly there are many who believe so. This is a hot topic on the talk and seminar circuit. After all, the proponents ask reasonably, who could object to making decisions based upon data? Two Types of Innovation: Incremental Improvements and New Concepts In design—and almost all innovation, for that matter—there are at least two distinct forms. One is
