摘　　要：针对波形套在轴向受压过程中,最佳轴向变形工作段轴向位移长度的优化问题,对波形套进行了轴向受压的有限元仿真研究,并对波形套的轴向力随压缩量的变化曲线进行了分析。根据波形套的几何参数,建立了正交试验组,并用Abaqus进行了数值模拟仿真;以正交试验的数据为基础,构造了波形套在受压过程中0.98倍~1倍的最大轴向力对应的最佳轴向变形工作段轴向位移长度的二阶响应面模型,并利用遗传算法对最佳轴向变形工作段轴向位移长度的二阶响应面模型进行了优化。研究结果表明:优化后的最佳轴向变形工作段轴向位移长度的响应结果与有限元计算结果相对误差为0.31%,说明响应面法可近似代替有限元法分析;通过这一方法,可在实际工程中为波形套驱动桥主动锥齿轮轴承预紧的设计提供依据。Aiming at the problem of optimization of the optimal axial displacement length of the working section of the corrugated sleeve under axial compression,the finite element simulation was carried out,and the curve of the axial force varying with the compression was analyzed.According to the geometric parameters of the corrugated sleeve,the orthogonal experimental group was established and simulated by Abaqus.Based on the orthogonal test data,a second-order response surface model of the optimal axial displacement length of the working section corresponding to the maximum axial force of 0.98 to 1 times of the corrugated sleeve in the compression process was constructed,and the genetic algorithm was used to optimize the model.The results show that the relative error between the optimized response and the finite element results is 0.31%,which indicates that the response surface method can approximately replace the finite element analysis.This method provides a basis for the preloading design of drive axle active bevel gear bearings in practical engineering.
