摘要
本机构资源库是在综合了前人智慧的基础上实现的，可供机械工程及其他技术人员在改造老产品和开发新产品设计时参考使用，可以帮助设计者精确选型，缩短设计周期，降低设计成本，这对加快创新开发和推动技术进步无疑具有重要意义。
本论文就是建立在对一些平面机构或机械产品结构简图的基础上，根据自己拟定的结构参数，采用SolidWorks进行三维建模和零件装配，然后采用COSMOSMotion进行运动和动力仿真分析，完成一些典型的连杆、凸轮、齿轮、螺旋等机构的设计与仿真，从而验证、修改、优化设计方案，使得以前需要组织研究团队，进行复杂设计计算，制造物理样机验证结果的设计过程大大简化。
第一章主要阐述了机构设计的概念及方法和物理样机及其技术；第二章简单地介绍了SolidWorks软件；第三章针对步进送料机构和凸轮机构，详细介绍了机构的建模、装配与仿真；第四章阐述了各机构的装配与仿真模型,主要包括飞机起落架的摆动导杆机构、起重机的曲柄滑块机构、轮子转向的螺旋连杆机构、手爪平行开闭的机械手、简易振动机、锯条的凸轮机构、增大行程的连杆齿轮组合机构、由曲柄滑块驱动的螺旋连杆机构、槽形凸轮驱动的直线运动机构、缝纫机的导杆球面机构等。

Abstract
The resource bank is a synthesis of the wisdom of our predecessors on the basis of the for mechanical engineering and other technical personnel in the transformation of old products and the development of new products using the reference design, can help designers accurate selection, shorten the design cycle, reduce design costs, This innovation to accelerate the development and promoting technological progress is undoubtedly of great significance.
This paper is based on the basis of some plane mechanisms or mechanical products' schematic structure. According to the structure drawn up by the parameters, use SolidWorks 3D modeling and assembly parts. Then use COSMOSMotion movtion and dynamic simulation analysis, complete the typical mechanisms of the link, cams, gears, spiral and other mechanisms design and simulation, then test, modify and optimize the design, made before the need to organize a group to study complex design and calculation, Manufacturing physical prototype test results greatly simplify the design process.
Chapter 1 mainly elaborates the concept and method of mechanisms’ design, and physical prototype and its technique; Chapter 2 introduces the software of SolidWorks in brief; Chapter 3 aims at a Step-feed mechanism and cam mechanism, introducing mechanism to set up a mold and assemble and simulation in detail; Chapter 4 elaborates each mechanism of assemble and simulation model, mainly include the airplane rises and falls of the swing lead the crank of pole mechanism, the crank and block mechanism of cranes, the screw connect pole mechanism of wheel steering, the hand-claw parallelism open to shut of machine hand, the simple vibration mechanism, the cam mechanism of saw, the enlarging a route of travel of the combination of pole gear mechanism, the crank and block mechanism of the screw connect pole mechanism, slot form the cam drive of the straight line mechanism, the spherical pole mechanism of sewing machine etc..
