摘　　要：利用商用软件Solidworks 2010建立了环板式行星分度凸轮机构的三维模型,并采用Solidworks2010运动插件进行了动力学仿真分析,获得了凸轮与针齿的接触力;建立了凸轮与针齿接触二维有限元模型,并对系统一个运动周期进行离散,接触分析计算得到凸轮与针齿接触的应力及应变。将分析结果与理论方法进行比较,表明有限元模型具有较高的分析精度,并能够准确地揭示受力状态和最大应力发生部位,为凸轮强度计算提供了可靠的依据。A prototype model of Ring-plate Planetary Indexing Cam Mechanism（RPICM） is developed with the commercial software of Solidworks 2010. The dynamics simulation using Solidworks 2010＇s Motion module is carried out, and the contact force of the cam and the pin gear is received. A 2D finite element model of the RPICM is established with Matlab and ANSYS software. This paper is aimed at the strain analysis of the cam With the finite element analysis （FEA）. The computations and analyses show the stress distribution and the place of the most stress. The results of FEA will provide a valuable reference for the structure design and the strength calculation in future research.
