通过合理地选择柔轮结构参数,可以改善柔轮的应力集中现象,提升柔轮的疲劳寿命。基于参数敏感性分析,筛选出影响柔轮应力的关键参数;以柔轮空载和负载过程中齿圈部位的最大等效应力最小以及谐波减速器整机的体积最小为优化目标,完成了柔轮参数响应面优化。通过疲劳计算发现,优化后的柔轮疲劳寿命有一定的提升。
The stress concentration effect can be reduced and the fatigue life of flexspline can be improved by reasonably selecting the structural parameters of flexspline. Based on the sensitivity analysis of parameters,the key parameters affecting the stress of the flexspline are screened out. The optimization objectives are to minimize the maximum equivalent stress of the gear ring and the volume of the harmonic reducer in the processes of no load as well as loading, the response surface optimization of flexspline parameters is completed. Through fatigue calculation,it is found that the life of the optimized flexspline is improved to a certain extent.
