1)前言: 在凸輪的加工过程中,由于存在着很难完全避免的工艺誤差,致使实际加工出的輪廓曲綫与設計的理論曲綫产生誤差,此种誤差的存在,对于低速工作的凸輪机构影响尚小,但对于高速凸輪却往往就是产生冲击和振动的主要原因,因而不能忽視。本文是应用有限差值法分析凸輪从动件的运动持性,从而可以显示出由于凸輪輪廓的誤差对其运动性質的影响。 1) Preface: Due to the process error that can hardly be avoided completely during the process of cam machining, the actually machined contour curve and the theoretical curve of the design are in error. The existence of such error affects the cam mechanism at low speed Still small, but for high-speed cam is often the main reason for the impact and vibration, and therefore can not be ignored. In this paper, the finite element method is used to analyze the kinematic of the cam follower, which can show the influence of the cam profile on the motion of the cam follower.
