摘     要
    
 随着人类社会的不断进步，科学技术的高速发展，机械在各行各业中得到了很好的运用。机械在国民生产中有着很重要的位置，它在很大程度上取代了原始的、落后的生产工具，它在现今中国和全世界的飞速发展的今天功不可没。本论文综述了机构设计在现代制造业中的意义和发展前景,还有机构的结构理论, 以及平行四边形、齿轮机构、凸轮机构、组合机构等的设计方法和设计要求，并简述了机构学领域的发展趋势，重点介绍机构资源库构建的先进方法。
 机构资源库是为了解决设计人员没有直观参考体而建立的，本次毕业设计所做的机构更是能够给出具体的三维模型和运动分析模型。机构的结构确定了组成机构的零部件的形式，它既确定了组成机构的连杆、运动副等的数量和类型，同时又确定了它们各自在由它们相互连接而构成机构中的行为。所以，机构资源库的建立意义非凡。本次毕业设计完成了由一个曲柄驱动的四组平行四边形机构，单偏心轮型双平行四边形机构,齿轮机构等典型机构的设计。通过SolidWorks的建模、装配、动力学仿真、应力分析、动画模拟等模块来设计完成。
关键词：机构  SolidWorks  建模  运动仿真
Abstract
 With the continuous progress of human society， the rapid development of science and technology， machinery in all walks of life have been very good to use. Machinery in the national product has a very important position. which to a large extent replaced the original behind the production tools， which in today''''s China and the world of today. The rapid development of credit. The graduation design constructed of institutional resources to the engineering and technical personnel to provide a selection of the optimal design of innovative programs platform. This paper summarized the design of modern manufacturing in the significance and prospects for development， Parallelogram，gears，cam mechanisms, portfolio agencies ，the composition of bodies such as the design methodology and design requirements， He briefed the field of institutional development trend focuses on building the institutional resources of the advanced methods-virtual technology;
 Agency resources to address the design did not directly refer to the establishment of the body, this body has done graduation project is to give a specific three-dimensional models and motion analysis model. Structure to form institutions to determine the form of components, the composition of both bodies to determine the link，deputy campaign, deputy of the number and type, etc, At the same time, identified by them in their mutual connection of the acts constitute a body . Therefore, it’s important to make a Resource agencies. This graduation design is through the SolidWorks modeling, assembly, dynamic simulation, stress analysis, animation simulation module to complete the simulation in virtual prototyping environment for technology, completed by a crank-driven parallelogram four groups of institutions in eccentric double parallelogram mechanism, gear mechanism, such as a typical body design and optimization.
