基于UGCAE的平面六杆机构的运动分析
基于UG/CAE的平面六杆机构的运动分析1、题目说明如上图所示平面六杆机构，试用计算机完成其运动分析。
已知其尺寸参数如下表所示：题目要求：两人一组计算出原动件从0到360时（计算点数37）所要求的各运动变量的大小，并绘出运动曲线图及轨迹曲线。
注：为了使计算的结果更好的拟合运动的实际情况，同时考虑到UG在运动仿真分析计算方面的快速性，我们决定在绘制曲线时将计算点由37点增加到600点。
数据输出到Excel表格时计算点取100点。
建模及其分析方法附后！2、建模及其运动分析软件介绍：UG NX是集CAD\CAE\CAM于一体的三维参数化软件，也是当今世界最先进的设计软件，它广泛应用于航空航天、汽车制造、机械电子等工程领域。
还有在系统创新、工业设计造型、无约束设计、装配设计、钣金设计、工程图设计等方面的功能。
运动仿真是UG/CAE（Computer Aided Engineering）模块中的主要部分，它能对任何二维或三维机构进行复杂的运动学分析、动力分析和设计仿真。
通过UG/Modeling的功能建立一个三维实体模型，利用UG/Motion的功能给三维实体模型的各个部件赋予一定的运动学特性，再在各个部件之间设立一定的连接关系既可建立一个运动仿真模型。
UG/Motion的功能可以对运动机构进行大量的装配分析工作、运动合理性分析工作，诸如干涉检查、轨迹包络等，得到大量运动机构的运动参数。
通过对这个运动仿真模型进行运动学或动力学运动分析就可以验证该运动机构设计的合理性，并且可以利用图形输出各个部件的位移、坐标、加速度、速度和力的变化情况，对运动机构进行优化。
我们通过学习UG，通过建立平面六杆机构模型，通过UG/CAE模块对平面连杆的运动进行分析。

UG运动仿真分析
· 固定副 在连杆间创建一个固定连接副，相当于以刚性连接两连杆，连杆间无相 对运动。
特殊运动副：
· 齿轮齿条副：滑动副和旋转副的结合 · 齿轮副：两个转动副的结合 · 线缆副：两个滑动副的结合 · 点线接触副：4个自由度 · 线线接触副： 4个自由度 · 点面副：5个自由度
UG提供了12种运动副共分两大类：普通运动副 8种，它是独特的，于自身有关；特殊运动副4种， 是在两个普通类型的运动副之间定义了特殊关系的 运动副，允许两个不同类型的运动副一起工作完成 特定的功能。
普通运动副
· 旋转副
连接两个连杆的经典运 动副，有 一个绕Z轴旋 转的自由度，不允 许两个连杆之间有任何的移动。
· 球铰
关节运动仿真，通过控制一个或多个原动运动副的位移步 长来进行机构动态仿真。位移为步长大小和步数的乘积。
· 生成图表
动画或关节仿真后，可通过图表方式输出机构的分析结果。 Y-轴：可通过下拉菜单设置Y轴参数。 值：‘幅值’和‘角度幅值’表示参数是各分量的合成量， T1，T2，T3和输入角度1、2、3分别表示所选参数的沿坐 标轴的三个水平分量或转动分量。
· 运动副
以一定的方式把各个构件彼此非刚性（可动）联接， 构件间能产生某些相对运动。
· 自由度和约束
任意两个没有构成运动副的构件，两者之间有6个 自由度（在坐标系中3个运动和3个转动）。若将两 者以某种方式联接而构成运动副，则两者的相对运 动便受到一定的约束。

基于UG的注塑模具研究一、本文概述随着现代制造业的快速发展，注塑模具作为塑料制品生产中的重要工艺装备，其设计、制造和应用水平直接影响到产品的质量和生产效率。
因此，对注塑模具的研究与改进一直是制造业领域的热点课题。
本文旨在探讨基于UG（Unigraphics N，一款广泛应用的CAD/CAM/CAE 集成软件）的注塑模具研究，通过对UG软件在注塑模具设计、分析、优化等方面的应用进行深入分析，以期提高注塑模具的设计效率、制造精度和使用性能。
本文将首先介绍注塑模具的基本原理和分类，阐述注塑模具在现代制造业中的重要地位和作用。
接着，重点分析UG软件在注塑模具设计中的应用，包括模具型腔设计、浇注系统设计、冷却系统设计等方面。
还将探讨UG软件在注塑模具分析和优化方面的功能，如模具流场分析、结构强度分析、热平衡分析等。

二、注塑模具基础知识注塑模具，亦称为塑料注射模具，是塑料加工工业中广泛使用的一种成型工具。
它的主要工作原理是，通过注塑机将熔融的塑料注入模具型腔，经冷却固化后，获得所需形状和尺寸的塑料制品。
注塑模具的设计、制造质量直接影响到产品的质量和生产效率，因此，对注塑模具的研究具有重要意义。
注塑模具通常由动模、定模两大部分组成，动模和定模在注塑机的合模机构作用下闭合，形成模具型腔。
模具型腔的形状和尺寸决定了塑料制品的外形和尺寸。
另外，注塑模具还包括浇注系统、导向机构、脱模机构、侧向分型与抽芯机构、温度调节系统等组成部分，这些部分共同保证了注塑过程的顺利进行。
在注塑模具的设计过程中，需要考虑的因素包括塑料的性能、产品的结构、注塑机的类型及规格、模具的制造工艺等。
设计合理的浇注系统可以保证塑料在模具型腔中均匀流动，避免产生气泡、缩孔等缺陷。
