施工组织设计的重要性

摘要:

建筑工程在施工过程中,施工组织方案的优劣不但直接影响工程的质量,对工期及施工过程中的人员安全也有重要影响。施工组织是

项目建设和指导工程施工的重要技术经济文件。能调节施工中人员、机器、原料、环境、工艺、设备、土建、安装、管理、生产等矛盾,要对施工组织设计进行监督和控制,才能科学合理的保证工程项目高质量、低成本、少耗能的完成。

项目管理施工组织方案重要性

施工组织设计就是对工程建设项目整个施工过程的构思设想和具体安排,是施工组织管理工作的核心和灵魂。其目的是使工程速度快、质量好、效益高。使整个工程在施工中获得相正确最优效果。

1.编制施工组织设计重要性的原因

建筑工程及其施工具有固定性与流动性、多样性与单件性、形体庞大与施工周期长这三对特点。因此,每一建筑工程的施工都必须进行施工组织设计。这是因为:其它一般工业产品的生产都有着自己固定的、长期适用的工厂。而建筑施工具有流动性的特点,不可能建立这样的工厂,只能是当每一个建筑工程施工时,建立一个相应的、临时性的,如同工厂作用性质的施工现场准备,即工地。施工单件性特点与施工流动性特点,决定了每一建筑工程施工都要选择相应的机具和劳动力组织。选择施工方法、拟定施工技术方案及其劳动力组织和机具配置,统称为施工作业能力配置。施工周期的特点,决定了各种劳动力、机具和众多材料物资技术的供应时间也比较长,这就产生了与施工总进度计划相适应的物资技术的施工组织设计内容。由此可见,施工组织设计在项目管理中是相当重要的。

2.施工组织设计方案的重要性

建筑产品作为一种商品,在项目管理中工程质量在整个施工过程中起着极其重要的作用。工程建设项目的施工组织设计与其工程造价有着密切的关系。施工组织设计基本的内容有:工程概况和施工条件的分析、施工方案、施工工艺、施工进度计划、施工总平面图。还有经济分析和施工准备工作计划。其中,施工方案及施工工艺的确定更为重要,如:施工机械的选择、水平运输方法的选择、土方的施工方法及主体结构的施工方法和施工工艺的选择等等,均直接影响着工程预算价格的变化。在保证工程质量和满足业主使用要求及工期要求的前提下,优化施工方案及施工工艺是控制投资和降低工程项目造价的重要措施和手段。

2.1施工组织方案在很大程度上影响着工程质量,因此合理的施工组织方案

不但是确保工程顺利完成的基础,也是工程安全的依据。施工组织设计是建筑工程设计文件的重要组成部分,是编制工程投资概预算的主要依据和编制招投标文件的主要参考依据。因此,认真做好施工组织设计,对于正确确定工程造价、降低工程投资,从而有利控制工程造价将有十分重要的作用。

2.2施工组织方案是对施工活动实行科学管理的重要手段,它具有战略部署和战术安排的双重作用。它体现了实现基本建设计划和设计的要求,提供了各阶段的施工准备工作内容,协调施工过程中各施工工区,各施工工种,各项自愿之间的相互关系。施工组织方案必须

能够根据工程产品的特点和要求,根据现有的和可能争取到的施工条件,从实际出发,决定各种生产要素的基本结合方式,不切实解决问题,就不可能进行任何生产。

3.施工组织设计的指标计算和分析

当前施工组织设计应建立哪些指标还不统一,计算方法也不规范。由于它是评价施工组织设计整体效果和评价执行状况的尺度,也是对承建工程施工的单位(项目部)生产经营管理水平和效果进行考核的依据。应予重视,提出如下意见。

3.1指标体系。指标体系的设置要尽量反映施工组织设计目标达到的水平,为评价、考核、执行提供方便。

3.2指标计算。(1)施工准备期。从现场准备开始到正式工程开工的全部时间。(2)单位工程工期。由单位工程施工进度计划安排的施工期。(3)劳动力不均衡系数。施工期高峰人数与平均人数之比。(4)降低成本额。技术组织措施降低成本的价格成果。(5)降低成本率。降低成本额占承包成本的百分比。(6)施工机械化程度。机械施工完成产值与工程承包造价之比。(7)工厂化施工程度。预制厂(采砂场、采石场)完成的产值与工程承包造价之比。(8)临时工程投资比例。全部临时工程投资与工程承包造价之比。(9)临时工程费用比例。全部临时工程消耗费用减回收费与工程承包造价之比。

3.3指标分析。施工组织设计指标与同类工程历史实际水平相比,能够评价施工组织设计效果;不同施工组织设计方案的指标对比,能够优选方案;分析以往历次同类工程的各项指标的加权数值,

冲压模具技术外文翻译(含外文文献)

前言 在目前激烈的市场竞争中,产品投入市场的迟早往往是成败的关键。模具是高质量、高效率的产品生产工具,模具开发周期占整个产品开发周期的主要部分。因此客户对模具开发周期要求越来越短,不少客户把模具的交货期放在第一位置,然后才是质量和价格。因此,如何在保证质量、控制成本的前提下加工模具是值得认真考虑的问题。模具加工工艺是一项先进的制造工艺,已成为重要发展方向,在航空航天、汽车、机械等各行业得到越来越广泛的应用。模具加工技术,可以提高制造业的综合效益和竞争力。研究和建立模具工艺数据库,为生产企业提供迫切需要的高速切削加工数据,对推广高速切削加工技术具有非常重要的意义。本文的主要目标就是构建一个冲压模具工艺过程,将模具制造企业在实际生产中结合刀具、工件、机床与企业自身的实际情况积累得高速切削加工实例、工艺参数和经验等数据有选择地存储到高速切削数据库中,不但可以节省大量的人力、物力、财力,而且可以指导高速加工生产实践,达到提高加工效率,降低刀具费用,获得更高的经济效益。 1.冲压的概念、特点及应用 冲压是利用安装在冲压设备(主要是压力机)上的模具对材料施加压力,使其产生分离或塑性变形,从而获得所需零件(俗称冲压或冲压件)的一种压力加工方法。冲压通常是在常温下对材料进行冷变形加工,且主要采用板料来加工成所需零件,所以也叫冷冲压或板料冲压。冲压是材料压力加工或塑性加工的主要方法之一,隶属于材料成型工程术。 冲压所使用的模具称为冲压模具,简称冲模。冲模是将材料(金属或非金属)批量加工成所需冲件的专用工具。冲模在冲压中至关重要,没有符合要求的冲模,批量冲压生产就难以进行;没有先进的冲模,先进的冲压工艺就无法实现。冲压工艺与模具、冲压设备和冲压材料构成冲压加工的三要素,只有它们相互结合才能得出冲压件。 与机械加工及塑性加工的其它方法相比,冲压加工无论在技术方面还是经济方面都具有许多独特的优点,主要表现如下; (1) 冲压加工的生产效率高,且操作方便,易于实现机械化与自动化。这是

附录一英文科技文献翻译 英文原文: Experimental investigation of laser surface textured parallel thrust bearings Performance enhancements by laser surface texturing (LST) of parallel-thrust bearings is experimentally investigated. Test results are compared with a theoretical model and good correlation is found over the relevant operating conditions. A compari- son of the performance of unidirectional and bi-directional partial-LST bearings with that of a baseline, untextured bearing is presented showing the bene?ts of LST in terms of increased clearance and reduced friction. KEY WORDS: ?uid ?lm bearings, slider bearings, surface texturing 1. Introduction The classical theory of hydrodynamic lubrication yields linear (Couette) velocity distribution with zero pressure gradients between smooth parallel surfaces under steady-state sliding. This results in an unstable hydrodynamic ?lm that would collapse under any external force acting normal to the surfaces. However, experience shows that stable lubricating ?lms can develop between parallel sliding surfaces, generally because of some mechanism that relaxes one or more of the assumptions of the classical theory. A stable ?uid ?lm with su?cient load-carrying capacity in parallel sliding surfaces can be obtained, for example, with macro or micro surface structure of di?erent types. These include waviness [1] and protruding microasperities [2–4]. A good literature review on the subject can be found in Ref. [5]. More recently, laser surface texturing (LST) [6–8], as well as inlet roughening by longitudinal or transverse grooves [9] were suggested to provide load capacity in parallel sliding. The inlet roughness concept of Tonder [9] is based on ??e?ective clearance‘‘ reduction in the sliding direction and in this respect it is identical to the par- tial-LST concept described in ref. [10] for generating hydrostatic e?ect in high-pressure mechanical seals. Very recently Wang et al. [11] demonstrated experimentally a doubling of the load-carrying capacity for the surface- texture design by reactive ion etching of SiC

控制系统基础论文中英文资料外文翻译文献 文献翻译 原文: Numerical Control One of the most fundamental concepts in the area of advanced manufacturing technologies is numerical control (NC).Prior to the advent of NC, all machine tools were manual operated and controlled. Among the many limitations associated with manual control machine tools, perhaps none is more prominent than the limitation of operator skills. With manual control, the quality of the product is directly related to and limited to the skills of the operator . Numerical control represents the first major step away from human control of machine tools. Numerical control means the control of machine tools and other manufacturing systems though the use of prerecorded, written symbolic instructions. Rather than operating a machine tool, an NC technician writes a program that issues operational instructions to the machine tool, For a machine tool to be numerically controlled , it must be interfaced with a device for accepting and decoding the p2ogrammed instructions, known as a reader. Numerical control was developed to overcome the limitation of human operator , and it has done so . Numerical control machines are more accurate than manually operated machines , they can produce parts more uniformly , they are faster, and the long-run tooling costs are lower . The development of NC led to the development of several other innovations in manufacturing technology: 1.Electrical discharge machining. https://www.360docs.net/doc/e315787625.html,ser cutting. 3.Electron beam welding.

机械设计理论 机械设计是一门通过设计新产品或者改进老产品来满足人类需求的应用技术科学。它涉及工程技术的各个领域,主要研究产品的尺寸、形状和详细结构的基本构思,还要研究产品在制造、销售和使用等方面的问题。 进行各种机械设计工作的人员通常被称为设计人员或者机械设计工程师。机械设计是一项创造性的工作。设计工程师不仅在工作上要有创造性,还必须在机械制图、运动学、工程材料、材料力学和机械制造工艺学等方面具有深厚的基础知识。如前所诉,机械设计的目的是生产能够满足人类需求的产品。发明、发现和科技知识本身并不一定能给人类带来好处,只有当它们被应用在产品上才能产生效益。因而,应该认识到在一个特定的产品进行设计之前,必须先确定人们是否需要这种产品。 应当把机械设计看成是机械设计人员运用创造性的才能进行产品设计、系统分析和制定产品的制造工艺学的一个良机。掌握工程基础知识要比熟记一些数据和公式更为重要。仅仅使用数据和公式是不足以在一个好的设计中做出所需的全部决定的。另一方面,应该认真精确的进行所有运算。例如,即使将一个小数点的位置放错,也会使正确的设计变成错误的。 一个好的设计人员应该勇于提出新的想法,而且愿意承担一定的风险,当新的方法不适用时,就使用原来的方法。因此,设计人员必须要有耐心,因为所花费的时间和努力并不能保证带来成功。一个全新的设计,要求屏弃许多陈旧的,为人们所熟知的方法。由于许多人墨守成规,这样做并不是一件容易的事。一位机械设计师应该不断地探索改进现有的产品的方法,在此过程中应该认真选择原有的、经过验证的设计原理,将其与未经过验证的新观念结合起来。 新设计本身会有许多缺陷和未能预料的问题发生,只有当这些缺陷和问题被解决之后,才能体现出新产品的优越性。因此,一个性能优越的产品诞生的同时,也伴随着较高的风险。应该强调的是,如果设计本身不要求采用全新的方法,就没有必要仅仅为了变革的目的而采用新方法。 在设计的初始阶段,应该允许设计人员充分发挥创造性,不受各种约束。即使产生了许多不切实际的想法,也会在设计的早期,即绘制图纸之前被改正掉。只有这样,才不致于堵塞创新的思路。通常,要提出几套设计方案,然后加以比较。很有可能在最后选定的方案中,采用了某些未被接受的方案中的一些想法。

Analysis,Applications Of Cams INTRODUCTION It is absolutely essential that a design engineer know how and why parts fail so that reliable machines that require minimum maintenance can be designed.Sometimes a failure can be serious,such as when a tire blows out on an automobile traveling at high speed.On the other hand,a failure may be no more than a nuisance.An example is the loosening of the radiator hose in an automobile cooling system.The consequence of this latter failure is usually the loss of some radiator coolant,a condition that is readily detected and corrected.The type of load a part absorbs is just as significant as the magnitude.Generally speaking,dynamic loads with direction reversals cause greater difficulty than static loads,and therefore,fatigue strength must be considered.Another concern is whether the material is ductile or brittle.For example,brittle materials are considered to be unacceptable where fatigue is involved. Many people mistakingly interpret the word failure to mean the actual breakage of a part.However,a design engineer must consider a broader understanding of what appreciable deformation occurs.A ductile material,however will deform a large amount prior to rupture.Excessive deformation,without fracture,may cause a machine to fail because the deformed part interferes with a moving second part.Therefore,a part fails(even if it has not physically broken)whenever it no longer fulfills its required function.Sometimes failure may be due to abnormal friction or vibration between two mating parts.Failure also may be due to a phenomenon called creep,which is the plastic flow of a material under load at elevated temperatures.In addition,the actual shape of a part may be responsible for failure.For example,stress concentrations due to sudden changes in contour must be taken into account.Evaluation of stress considerations is especially important when there are dynamic loads with direction reversals and the material is not very ductile. In general,the design engineer must consider all possible modes of failure,which include the following. ——Stress ——Deformation ——Wear ——Corrosion ——Vibration ——Environmental damage ——Loosening of fastening devices

外文文献原文: Friction , Lubrication of Bearing In many of the problem thus far , the student has been asked to disregard or neglect friction . Actually , friction is present to some degree whenever two parts are in contact and move on each other. The term friction refers to the resistance of two or more parts to movement. Friction is harmful or valuable depending upon where it occurs. friction is necessary for fastening devices such as screws and rivets which depend upon friction to hold the fastener and the parts together. Belt drivers, brakes, and tires are additional applications where friction is necessary. The friction of moving parts in a machine is harmful because it reduces the mechanical advantage of the device. The heat produced by friction is lost energy because no work takes place. Also , greater power is required to overcome the increased friction. Heat is destructive in that it causes expansion. Expansion may cause a bearing or sliding surface to fit tighter. If a great enough pressure builds up because made from low temperature materials may melt. There are three types of friction which must be overcome in moving parts: (1)starting, (2)sliding, and(3)rolling. Starting friction is the friction between two solids that tend to resist movement. When two parts are at a state of rest, the surface irregularities of both parts tend to interlock and form a wedging action. To produce motion in these parts, the wedge-shaped peaks and valleys of the stationary surfaces must be made to slide out and over each other. The rougher the two surfaces, the greater is starting friction resulting from their movement . Since there is usually no fixed pattern between the peaks and valleys of two mating parts, the irregularities do not interlock once the parts are in motion but slide over each other. The friction of the two surfaces is known as sliding friction. As shown in figure ,starting friction is always greater than sliding friction . Rolling friction occurs when roller devces are subjected to tremendous stress which cause the parts to change shape or deform. Under these conditions, the material in front of a roller tends to pile up and forces the object to roll slightly uphill. This changing of shape , known as deformation, causes a movement of molecules. As a result ,heat is produced from the added energy required to keep the parts turning and overcome friction. The friction caused by the wedging action of surface irregularities can be overcome

译文 流体传动及控制技术已经成为工业自动化的重要技术,是机电一体化技术的核心组成之一。而电液比例控制是该门技术中最具生命力的一个分支。比例元件对介质清洁度要求不高,价廉,所提供的静、动态响应能够满足大部分工业领域的使用要求,在某些方面已经毫不逊色于伺服阀。比例控制技术具有广阔的工业应用前景。但目前在实际工程应用中使用电液比例阀构建闭环控制系统的还不多,其设计理论不够完善,有待进一步的探索,因此,对这种比例闭环控制系统的研究有重要的理论价值和实践意义。本论文以铜电解自动生产线中的主要设备——铣耳机作为研究对象,在分析铣耳机组各构成部件的基础上,首先重点分析了铣耳机的关键零件——铣刀的几何参数、结构及切削性能,并进行了实验。用电液比例方向节流阀、减压阀、直流直线测速传感器等元件设计了电液比例闭环速度控制系统,对铣耳机纵向进给装置的速度进行控制。论文对多个液压阀的复合作用作了理论上的深入分析,着重建立了带压差补偿型的电液比例闭环速度控制系统的数学模型,利用计算机工程软件,研究分析了系统及各个组成环节的静、动态性能,设计了合理的校正器,使设计系统性能更好地满足实际生产需要 水池拖车是做船舶性能试验的基本设备,其作用是拖曳船模或其他模型在试验水池中作匀速运动,以测量速度稳定后的船舶性能相关参数,达到预报和验证船型设计优劣的目的。由于拖车稳速精度直接影响到模型运动速度和试验结果的精度,因而必须配有高精度和抗扰性能良好的车速控制系统,以保证拖车运动的稳速精度。本文完成了对试验水池拖车全数字直流调速控制系统的设计和实现。本文对试验水池拖车工作原理进行了详细的介绍和分析,结合该控制系统性能指标要求,确定采用四台直流电机作为四台车轮的驱动电机。设计了电流环、转速环双闭环的直流调速控制方案,并且采用转矩主从控制模式有效的解决了拖车上四台直流驱动电机理论上的速度同步和负载平衡等问题。由于拖车要经常在轨道上做反复运动,拖动系统必须要采用可逆调速系统,论文中重点研究了逻辑无环流可逆调速系统。大型直流电机调速系统一般采用晶闸管整流技术来实现,本文给出了晶闸管整流装置和直流电机的数学模型,根据此模型分别完成了电流坏和转速环的设计和分析验证。针对该系统中的非线性、时变性和外界扰动等因素,本文将模糊控制和PI控制相结合,设计了模糊自整定PI控制器,并给出了模糊控制的查询表。本文在系统基本构成及工程实现中,介绍了西门子公司生产的SIMOREGDC Master 6RA70全数字直流调速装置,并设计了该调速装置的启动操作步骤及参数设置。完成了该系统的远程监控功能设计,大大方便和简化了对试验水池拖车的控制。对全数字直流调速控制系统进行了EMC设计,提高了系统的抗干扰能力。本文最后通过数字仿真得到了该系统在常规PI控制器和模糊自整定PI控制器下的控制效果,并给出了系统在现场调试运行时的试验结果波形。经过一段时间的试运行工作证明该系统工作良好,达到了预期的设计目的。 提升装置在工业中应用极为普遍,其动力机构多采用电液比例阀或电液伺服阀控制液压马达或液压缸,以阀控马达或阀控缸来实现上升、下降以及速度控制。电液比例控制和电液伺服控制投资成本较高,维护要求高,且提升过程中存在速度误差及抖动现象,影响了正常生产。为满足生产要求,提高生产效率,需要研究一种新的控制方法来解决这些不足。随着科学技术的飞速发展,计算机技术在液压领域中的应用促进了电液数字控制技术的产生和发展,也使液压元件的数字化成为液压技术发展的必然趋势。本文以铅电解残阳极洗涤生产线中的提升装置为研究

P. - Lecturer, KSR College of Technology, Tiruchengode–637 215, TamilNadu, India Ananthakrishnan, T.- Professor and Head, Department of Textile Technology, Government Sri Krishna Rajendra silver jubilee Technical Institute, Bangalore – 560 001, India Abstract Drape of the fabric is its ability to hang freely in graceful folds when some area of it is supported over a surface and the rest is unsupported. Drape is a unique property that allows a fabric to be bent in more than in one direction, When two-dimensional fabric are converted to three-dimensional garment form. In the present study, the effects of sewing of different seam were selected on different fabric and their behaviors were studied. In this study drape of ten fabrics are analyzed with three types of seams and three stitch densities. Sample without seam is a control sample and drape of seamed samples are compared with control sample to analyse the drape behavior of seamed fabrics. This paper presents a fundamental drape analysis of seamed fabrics using drape meter. Drape behavior is determined in terms of drape coefficient. The effect of seams on the drape coefficient and Drape profile has been made. Drape coefficients significantly differs between the fabrics and also between the seam stitch density combinations. Investigating drape on seamed fabrics can improve fabric end use application.
