摘　　要：将CAD技术应用到包装箱取放共轭凸轮多连杆机构中,进行了设计、建模及仿真。基于SolidWork草图功能,应用自上而下的方法对多连杆机构进行设计,应用Motion插件对共轭凸轮轮廓进行反求设计并进行三维建模,考虑凸轮与滚子的碰撞接触,在ADAMS中添加接触力并进行仿真分析。仿真结果表明能实现包装箱取放及开箱的既定动作,且误差较小,共轭凸轮机构的摆臂角加速度最大值为58°/s2,柔性冲击,考虑凸轮与滚子的接触碰撞对摆臂角加速度影响较大,最大值为1 398°/s2,接触力出现腾跳现象。设计方法方便准确,省去了繁琐计算,考虑接触碰撞会影响机构运行稳定性,为机构凸轮曲线优化提供依据,同时也为相关产品的研发提供了有效的设计方法。The work aims to integrate CAD technology into the design modeling and simulation of conjugate cam multi link mechanism for taking and placing packaging cases.The Top-Down method is used to design the multi link mechanism based on the SolidWork sketch.It is reverse designed for conjugate cam contour application the Motion plug-in.Considering the collision contact between cam and roller,the contact force is added and simulated based on ADAMS.The simulation results show that the set action of taking and placing the packaging box and unpacking can be realized,and the error is small.The maximum angular acceleration of the swing arm of the conjugate cam mechanism is58°/s2,and the flexible impact.Considering the contact collision between the cam and the roller,the angular acceleration of the swing arm is greatly affected,and the maximum value is 1 398°/s2,and the contact force appears jumping phenomenon.The design method is convenient and accurate,eliminating cumbersome calculations.Considering that contact and collision will affect the operating stability of the mechanism,it provides a basis for the optimization of the cam curve of the mechanism,and also provides an effective design method for the research and development of related products.
