摘 要
小汽车举升机的三维设计是在认真思考了现有的各种起重设备和实际工作条件的情况下，从而进行的举升机的剪式结构的设计。在设计中完全考虑到安全和使用要求，结合计算机技术来优化举升机设计，以实现不同客户需求，不同小汽车型号的需求。
经过初期的结构设计，参数设置以及力学分析给出整体的合理型式，再通过SolidWorks建立各零部件的三维建模，并结合虚拟装配，，最后举升机工作过程的仿真是通过SolidWorks的运动仿真功能来实现，以检验整套装置的合理性和灵活性。

Abstract
    Three-dimensional design of the car lift is seriously considering lifting equipment under actual working conditions and the existing design of the scissor lift structure thus conducted. Fully taken into account in the design of the safety and use requirements, combined with computer technology to optimize the lift design to fulfill customer needs, different needs of different car models.
By the preliminary structural design, parameter setting and the mechanical analysis gives a whole reasonable type. Then use SolidWorks establish various parts of the three-dimensional modeling, and realize the Virtual Assembly. Finally, though the motion simulation function of SolidWorks realize the working process simulation of Lifter, to test the rationality, flexibility of the entire device.
