摘　　要：文中针对柔轮结构设计中寿命与承载能力差、易失效等问题,首先对柔轮进行参数化建模,然后基于有限元分析软件对在波发生器装配下的柔轮进行静力学分析,以柔轮长度、壁厚、齿宽以及筒体圆角半径作为变量,柔轮最大等效应力作为优化目标设计正交试验,并通过极差分析对所选取的结构参数进行重新组合以达到结构优化目标。结果表明,通过正交试验得出各参数对空载状态下柔轮最大等效应力的影响程度为柔轮长度>齿宽>壁厚>筒底圆角半径,极差分析后对结构参数进行组合并进行建模仿真,使柔轮最大等效应力减小了32.43%,为柔轮的结构优化提供参考。Considering the problems of poor life and bearing capacity and easy failure in the structural design of flexspline,firstly,a parametric model of flexspline was established,and then a static analysis of flexspline assembled with wave generator was carried out based on finite element analysis software.Taking the length,wall thickness,tooth width and radius of cylinder fillet of flexspline as variables and the maximum equivalent stress of flexspline as the optimization objective,an orthogonal test was designed,and the selected structural parameters were recombined through range analysis to achieve structural optimization.Results show that the influence degree of each parameter on the maximum equivalent stress of flexspline under no-load condition is as follows:flexspline length>tooth width>wall thickness>fillet radius of cylinder bottom.After range analysis,the structural parameters were combined and simulated,and the maximum equivalent stress of flexspline was reduced by 32.43%,which provides reference for structural optimization of flexspline.
