Abstract The stress concentration effect can be reduced and the fatigue life of flexspline can be im-proved by reasonably selecting the structural parameters of flexspline. Based on the sensitivity analysis of param-eters，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 pro-cesses 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 .
