摘　　要：提出了精确反求凸轮从动件运动规律的方法.利用三坐标测量机获得凸轮机构的基本尺寸,将测头半径补偿后的数据在Matlab中进行二次光顺,并借助光顺后的数据进行运动学公式的反求推导,凭借Matlab强大的数值计算、编程和绘图功能,得出了凸轮从动件的运动规律.通过与常用运动规律的分析和比较,实现了运动规律的精确反求.A method for precise reverse of cam follower movement law is put forward. The basic dimensions of cam mechanism is obtained by coordinate measuring machine. The radius compensation data after measuring head is second smoothed in Matlab. The reverse deduction of kinematical equation is done with smoothed data. Then the movement law of cam follower is achieved by Matlab＇s strong function of numerical calculation, programme and plot. The movement law is precisely reversed by comparison and analysis to the common movement.
