Comfortableness of cars is influenced obviously by engine vibration. Aiming at the vibration problem of passenger cars, this paper presents an optimal method for powertrain mounting system which bases on energy decoupling method. Firstly, a six-freedom dynamic model of powertrain mounting system of passenger cars is established. Then, an optimal process of mounting system is conducted by using the theory of energy decoupling with maximizing decoupling rate of the six-freedom mounting system as objective. The theory of energy decoupling and the elastic theory are applied to optimize the design of powertrain mounting system in Matlab software. Powertrain mounting system is implemented by ADAMS software. At last, optimal results of Matlab and ADAMS are compared. The comparison results illustrate effectiveness and rationality.
