- Summary:
- A dynamic performance calculating model for a powertrain-subframe mounting system (PSMS) is presented. Calculation methods for determining the dynamic dis-placements of a powertrain center of gravity (CG), the dynamic displacements of a subframe CG and the dynamic reaction forces of each mount in a PSMS under ground and motor shake excitation are developed in this paper. Then the amplitude versus frequency responses of the dynamic displacements of a powertrain CG, the dynamic displacements of a subframe CG and the dynamic reaction forces of each mount are estimated for an electrical vehicle PSMS. The calculation results using 6 dof (degrees of freedom) powertrain mounting system (PMS) model and 12 dof PSMS model are compared and analyzed. The calculation results demonstrate that the results using PSMS can get more accurate, the calculation methods can be used for reducing vibra-tions of powertrain and car body
