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.
