摘  要
 本论文首先对机构设计的意义、机构的形式设计、机构的选型、构型、机构的概念设计、虚拟样机技术等相关理论进行消化理解。并在此基础上通过SolidWorks三维机械设计软件对典型的连杆机构、凸轮机构、齿轮机构、螺旋机构等机构零部件的三位建模，然后对这些零部件进行装配，形成装配模型。通过SolidWorks的插件COSMOSMotion对已经完成的机构模型进行运动仿真，分析该机构的运动轨迹，作用力、反作用力、速度、加速度、位移随时间变化的曲线，输出仿真结果。根据仿真的结果数据，对机构运行原理有了更深一层次的理解，并对进行创新设计，为机构资源库提供细胞单元，为构建机构资源库作出贡献。机电产品的设计都是为了满足某种特定的功能要求，而这些功能要求往往是通过机构的动作来实现，这些典型机构就是机电产品的技术关键所在。机构学是机械设计及理论二级学科的重要分支，是机械设计理论中不可替代的基础研究内容。由于机构学是研究机构与机器的分析和综合的理论，因此它对于机械产品创新设计和高新技术在机械产品中应用显得十分重要。机构创新设计决定了产品的创新性，对产品的创新而言，机构拓扑创新设计具有原创的特征性质，是机械发明中最具有挑战性和发明性的核心内容。

Abstract
 Paper first to set-up design significance, Set-up form design, Set-up shaping, Configuration，Set-up conceptual design, The dummy specimen technology and so on the correlation theories carries on the digestion understanding. And in this foundation through SolidWorks three dimensional machine design software to model link motion gear, Cam gear, Gear mechanism, Set-up spare part and so on spiral set-up three modellings，Then carries on the assembly to these spare parts, Forms the assembly model. In to the set-up model which already completes carries on the movement simulation through SolidWorks plug-in unit COSMOSMotion，Analyzes this set-up the path, Action, reacting force, speed, acceleration, displacement along with time variation curve, The output simulation result, and to carries on the innovation design, provides the cell unit for the set-up resources storehouse, is the construction set-up resources storehouse makes the contribution.The mechanical and electrical products design all is in order to satisfy some kind of specific function request, But these function request often is realizes through the set-up movement, These commonly used set-ups are the mechanical and electrical products technical key are at. Mechanism is the machine design and the theory two level of discipline important branch, Is basic research content which in the machine design theory cannot be substituted.Because mechanism is the development facility and the machine analysis and the synthesis theory, Therefore it applies regarding the mechanical product innovation design and the high technology and new technology in the mechanical product appears extremely importantly. The set-up innovation design has decided the product innovation, Speaking of the product innovation, The set-up analysis situs innovation design has the original characteristic nature, Is in the machinery invention most has the challenging and the inventive core content.
