针对包裹机推料机构结构复杂和求解凸轮轮廓曲线困难的问题，提出了采用ADAMS设计凸轮轮廓曲线的方法。通过机构分析，建立了推料机构的虚拟样机模型；然后进行了推料板的轨迹规划，通过ADAMS的自动动力学和逆动力学解算得到了摆杆的运动曲线，在此基础上利用反转法和ADAMS的create trace spline功能，得到了凸轮的轮廓曲线；对设计出的凸轮机构进行了正动力学仿真，通过对推料板的运动轨迹和规划轨迹进行一致性比较，验证了该方法的可行性。

A new design method of cam contour curve based on ADAMS was put forward to solve the difficult problem of designing cam contour curve for the complicated structure of packaging machine pusher mechanism. The virtual prototype of the pusher mechanism was built according to mechanism analysis of the pusher. The trajectory of the pusher plate was planned based on the virtual pusher mechanism model and the kinetic curves of two swing stems were obtained through the automatic dynamic and inverse dynamic solving of ADAMS. Then the cam contour curves can be obtained through the rollback method and the create trace spline function of ADAMS. The feasibility of this method was verified through consistence comparison between the planned trajectory and the forward dynamic simulation trajectory.
