英文摘要：

The simplified dynamic modeling of cam mechanisms is given according to finite-segment method, and the kinematic analyses of this dynamic modeling are obtained. Furthermore, the dynamic equations of cam mechanisms with beam-like flexible members are established based on Kane＇s equations. The computer program of analysis for high-speed cam mechanisms is formed according to the dynamic equations. Numerical results show that the finite-segment method is a better procedure for the dynamic analysis of high-speed cam mechanisms.
