摘　　要：目的基于SW二次开发,为食品包装设备开发专用的整机凸轮连杆机构设计分析系统;利用SW为整机执行件运动的稳定性和不干涉性提供一种直观的评估方法。方法根据执行件的运动形式和凸轮连杆机构的结构形式,基于SW 3D建模软件,利用VS作为开发工具搭建C++开发环境,从而构建整机凸轮连杆CAD系统。将整机执行件作为研究对象,利用ADAMS和Ansys进行刚柔耦合仿真分析。研究主受力杆件和细长杆件柔性化对整机执行件稳定性和不干涉性的影响,从而验证此系统设计整机凸轮连杆机构的合理性。结果在高速条件下,对整机凸轮连杆机构进行刚柔耦合仿真,其结果符合动作时序设计要求。上冲执行件位移最大偏差率为0.08%,速度最大偏差率为0.05%,加速度与理论设计基本相符,因此具有较好的稳定性和不干涉性。结论刚柔耦合仿真结果能正确地反映整机执行件运动过程的稳定性和不干涉性,从而验证了此系统设计整机凸轮连杆机构的合理性。The work aims to develop a special design and analysis system for the whole machine cam linkage mechanism of food packaging equipment based on the secondary development of SW and provide an intuitive evaluation method for the stability and non-interference of the whole machine actuator movement by virtue of SW.According to the movement form of the actuator and the structure form of the cam linkage mechanism,VS was used as the development tool to build the C++development environment based on SW 3D modeling tool to develop the CAD system of the whole machine cam linkage.The whole machine actuator was taken as the research object.ADAMS and Ansys were adopted to complete simulation analysis of rigid flexible coupling.The influences of the flexibility of the main load-bearing bar and the slender bar on the stability and non-interference of the whole actuator were studied,to verify the rationality of the design of the whole machine cam linkage mechanism.The rigid flexible coupling simulation of the whole machine cam linkage mechanism was completed at high speed.The results met the design requirements of action sequence.The maximum deviation rate of the displacement of the upper punch actuator was 0.08%;and the maximum deviation rate of the speed was 0.05%.The acceleration was basically consistent with the theoretical design,so it had good stability and non-interference.The results of rigid flexible coupling simulation can correctly reflect the stability and non-interference of the whole machine actuator movement process,which verifies the rationality of the system design of the whole machine cam linkage mechanism.
