摘　　要：用瞬心法对直动从动件凸轮机构进行高副低代得到了等效曲柄滑块机构,推导出了各速度瞬心之间的几何运动关系,论述了凸轮廓线曲率半径图解法的原理,介绍了高速、高精度地计算凸轮廓线曲率半径的CAD动画方法。By using the instantaneous velocity center method to the equivalent crank and slide lump mechanism of the cam mechanism with straight moving follower, this paper sets up geometric and kinematic relationships between instantaneous velocity centers, it studies the principle of a new graphic method for determing the radius of curvature of planar cam profile.Then CAD animation mothed for computing the radius of curvature of planar cam profile is introduced.
