摘要

基于实验设计方法,仿真分析了汽车动力总成悬置系统解耦布置的鲁棒性。以某款车的动力总成悬置系统为例,计算了悬置静刚度对悬置系统固有频率和解耦率变化的贡献率,识别出了对悬置系统解耦布置影响较大的悬置静刚度参数。算例结果表明,悬置系统固有频率和解耦率的变化是多个刚度参数共同作用的结果,悬置系统三个平动方向的固有频率和解耦率受刚度参数变化的影响较小,三个转动方向的固有频率和解耦率受刚度参数变化的影响较大。文中方法为设计解耦布置优良、稳健的动力总成悬置系统提供了一般的分析方法和理论依据。

Abstract

A computer aided engineering (CAE) based design of experiment (DOE) is used to analyze the robustness for the decoupling layout of a powertrain mounting system (PMS). The PMS of a car is considered, and contributions of the mount stiffness parameters to variations of the frequencies and the decoupling ratios of the PMS are investigated, respectively. The analysis method discloses the key stiffness parameters for the robustness of the frequencies and the decoupling ratios of the PMS. Analysis results show that variations of the frequencies and the decoupling ratios are due to the variations of all the stiffness parameters. The variations of the stiffness parameters have more influence on the frequencies and the decoupling ratios in the three rotational directions than that in the three translational directions of the PMS. The presented robustness analysis method lays theoretical foundations for the robustness design of a generic PMS.
