摘　　要：提出了利用样本函数与一个常数乘积的积分获得凸轮从动件运动规律的方法,导出了常见的幂函数类、三角函数类和指数函数类运动规律的表达式,得到了七、九、十一次幂函数及次摆线函数等高阶导数连续的凸轮从动件运动规律,并给出了几种重要规律的特性值,对四次幂修正等速度及简谐修正等速度规律进行了补充讨论.Thoughts are introduced that the integral of the product of the sample function and a constant is used to get cam follower motion law in this paper.The movement rule expressions of common power function classes,trigonometry function classes and exponential function classes are derived.Seventh,ninth and eleventh times power function and times cycloid function are obtained which higher order derivative are continuous for motion rule of cam follower.The characteristics values of several important laws are given.The laws of four times power amend constant velocity and simple harmonic amend constant velocity are added for discussion.
