UG在仿真运动中应用毕业设计.doc

题目： UG在仿真运动中的应用 姓名： 学号： 系部： 机电工程系 专业： 机电一体化 指导老师： 提交时间： 摘要 UG是目前市场上功能最极致的产品设计工具。它不但拥有现今CAD/CAM软体中功能最强大的Parasolid实体建模核心技术，更提供高效能的曲面建构能力，能够完成最复杂的造形设计。UG提供工业标准之人机介面，不但易学易用，更有无限次数的undo功能、方便好用的弹出视窗指令、快速图像操作说明、自订操作功能指令及中文化操作介面等特色，并且拥有一个强固的档案转换工具，能转换各种不同CAD应用软体的图档，以重复使用旧有资料。 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。 目录 概述··························································· 第一章 建模··························································· 1.0 机架的设计··············································· 1.1 轴1的设计·············································· 1.2 连杆的设计················································ 1.3 轴2的设计············································· 1.4 活塞的设计············································ 第二章 零件装配与爆炸图································· 2.0 配对·············································· 2.1 对齐·············································· 2.2 距离·············································· 2.3 改变约束·············································· 2.4 创建爆炸图··············································· 2.5 自动爆炸组件··············································· 2.6 编辑爆炸图··············································· 第三章 运动仿真··············································· 4.0 建立连杆·············································· 4.1 建立旋转副·············································· 4.2 建立滑动副·············································· 4.3 求解动画·············································· 概 述 运动仿真在UG中是比较重要的部分，其主要内容有： 对装配好的模型建立连杆 在连杆的基础上建立旋转副 在连杆中建立一个滑动副。 解算方案并求解 设计目的及要求： 毕业设计能更好的体现我们在学校期间学到的理论知识和实践的综合情况。不仅复习了我们三年学习的内容，而且在我们即将毕业进入社会奠定了一定的专业基础。 首先每一个零件都必需符合书本上的要求，比如说做草图时要有一定的约束。其次是要联系
