摘要

为满足汽车动力总成悬置系统匹配过程中悬置的刚度要求，本文对悬置中非橡胶填充结构进行优化设计，以长槽的半径r，圆槽的半径R，两槽间的夹角α，长槽的角度β为结构参数，采取正交实验与ABAQUS有限元软件结合的方法，对橡胶悬置刚度进行仿真实验。根据实验结果建立二阶响应面模型，通过谢菲尔德遗传算法进行优化，从而获取非橡胶填充结构参数以满足悬置刚度要求。优化结果与试验验证误差较小，满足设计要求。该方法在橡胶悬置设计阶段具有参考意义。

Abstract

To meet mount stiffness requirement for vibration isolation of powertrain, a method for optimizing non-rubber filled structure of a powertrain mount is proposed. The optimized structural parameters are the radius of the long groove, the radius of the circular groove, the angle between the two grooves α and the angle β of the long groove. The orthogonal experiment and ABAQUS finite element software were used to estimate the stiffness of rubber mount.A second-order response surface model was established and optimized by using the Sheffield Genetic Algorithm to obtain the non-rubber filling structure parameters to meet stiffness requirements .
