摘　　要：为了优化双圆弧谐波减速器中的柔轮结构,使用SoildWorks软件建立双圆弧齿廓的柔轮三维模型,利用有限元法模拟在装配条件下波发生器对柔轮的变形并建立了接触模型。针对柔轮轮齿上倒角的角度和薄壁圆筒壁厚等结构参数进行了优化,通过ANSYS Workbench对比分析了柔轮在空载和负载情况下,柔轮轮齿上最大等效应力和薄壁圆筒最大等效应力随柔轮结构参数的变化规律。研究为优化谐波减速器中柔轮的结构设计提供了依据,为空载和负载时柔轮的受力分布情况提供了参考。In order to optimize the structure of the flexspline in the double-arc harmonic reducer,the three-dimensional model of the flexspline with double arc tooth profile is established by using the SoildWorks software,and the deformation of the flexspline by the wave generator under the assembly condition is simulated by using the finite element method and the contact model is established.According to the structural parameters of the flexspline,including the chamfer angle of the flexspline and the wall thickness of the thin-walled cylinder,the optimization is carried out,the change of the maximum equivalent stress on the teeth of the flexspline and the maximum equivalent stress of the thin-walled cylinder with the structural parameters of the flexspline are analyzed by the ANSYS Workbench.This study provides the basis for optimizing the structure design of the flexspline in the harmonic reducer,and provides the basic reference for the force distribution of the flexspline under no load and load.
