The authors describe the evaluation methods of automotive powertrain mounting system performance, in-cluding the decoupling target analysis of the design stage, the modal analysis of powertrain rigid body, focus on the analysis of relationship between the vehicle suspension system vibration isolation rate associated with the vehicle vi-bration based on experiment, and obtain the more effective and reasonable evaluation for the mounting system per-formance of vibration isolation.
