摘　　要：通过瞬心法进行高副低代,得到了摆动从动件凸轮机构的等效四杆机构;在此基础上,论述了凸轮廓线曲率半径图解法的原理,给出了它们之间的几何运动关系。进一步讨论了采用CAD动画的方法,高速高精度地计算凸轮廓线曲率半径的过程。Through application of polar method to the equivalent four bar linkage of the cam mechanism, the principle of a new graphic method for determing the radius of curvature of planar cam profile is studied, the geometric and kinematic relationships are given. Then the process for computing the radius of curvature of planar cam profile is introduced by means of CAD animation.
