前言从动杆系弹性较大的凸轮传动,例如,内燃机、纺织机以及某些自动控制机构中的凸轮——从动件系统,在高速运转情况下,由从动杆系质量弹性反映而引起的运动及动力差别,相当显著。此种差剧不仅影响凸输机构对运动控制的精确性,更重要的是它常常是从动件与凸轮高付之间引起纵向“撞击”现象的原因之一,而且,随之产生的瞬态振动,在较严重的情况下,将破坏机构的正常循环工作。凸轮的廓线形状与从动系的运动特性和振动状态,有直接的影响。本文对在高速机构中较常采用的摆线位移凸轮及简谐运动凸轮机构在考虑构件弹性条 Introduction Driven rod systems are more flexible cam drives, such as cam-follower systems in internal combustion engines, textile machines, and some automatic control mechanisms, which are caused by the elastic mass of the driven rod system at high speeds The difference of movement and power is quite remarkable. This bad play not only affects the accuracy of the motion control of the bump mechanism, but more importantly it is often one of the causes of the longitudinal “bump” between the follower and the cam, and the resulting momentary State vibration, in more serious cases, will undermine the normal circulation of institutions. The profile of the cam has a direct effect on the kinematics and vibrations of the driven system. In this paper, the more commonly used in high-speed mechanism cycloid cam and simple harmonic motion cam mechanism in the consideration of the elastic member
