摘　　要：针对目前中空超扁平系列谐波减速器在运行过程中,存在柔轮易发生疲劳损坏,其疲劳寿命严重制约着谐波齿轮减速器的使用寿命等问题,课题组基于有限元仿真软件HyperMash,研究了中空超扁平系列谐波减速器柔轮的应力特性和疲劳寿命;并分析载荷、齿长、齿厚和柔轮高度等参数对应力和疲劳寿命的影响。研究结果表明载荷是影响柔轮疲劳寿命最主要的因素。该研究可为后续机械结构优化提供参考。In view of the fact that the flexible wheels are most prone to fatigue damage during the operation of hollow super flat series harmonic reducers,and their fatigue life seriously restricts the service life of the harmonic gear reducers,the stress characteristics and fatigue life of those flexible wheels were studied based on the finite element simulation software HyperMash.The influences of load,gear length,gear thickness and flexible wheel height on the stress and fatigue life were analyzed.The results show that the load is the most important factor affecting the fatigue life of flexible wheels.This conclusion can provide guidance for the follow-up mechanical structure optimization.
