摘　　要：针对凸轮端从动件运动规律不能用解析函数式表示或者表达式比较复杂时,导致工作端的激振函数只能用离散的数值表示的情况,研究凸轮机构动态分析问题。建立数学模型及动力学方程,采用数值分析法对高速凸轮机构的输入、输出的动态响应及误差进行研究,运用MATLAB软件调用数值微分函数对高速凸轮从动端及工作端的位移、速度、加速度及两者间的误差进行分析。证实了数值分析法在研究高速凸轮机构动态分析方面具有一定的优越性。同时该研究也为高速凸轮机构动态优化设计提供新的理论依据。Aiming at that end CAM follower motion cannot be expressed in analytic function or that the expression is more complex,it leads to the situation that the working end on the excitation function can only use the discrete numerical representation,studies the problem of the dynamic analysis of CAM mechanism. Establish mathematical model and dynamic equation,and the numerical analysis of high speed CAM mechanism of the input,output of the dynamic response and error are studied,using MATLAB software to carry on numerical differential displacement function,analyzes the high speed cam driven end and a working end displacement,speed,and acceleration or the error between the two. It confirms that numerical analysis method in the study of high speed CAM mechanism dynamic analysis has certain advantages. Also the study for the high-speed CAM mechanism and dynamic optimization design provides a new theoretical basis.
