Simulation of the Vibration Isolation Performance of Power Train Mount System of Truck

In this paper, a six-degree-of-freedom model of power train mount system is set up by using the software ADAMS. The effects of mount parameters on the vibration isolation performance of power train mount system are investigated by using parameter analysis method. Mount parameters are taken as design variable of the optimization design of the vibration isolation , and the minimum force in support area on the vehicle boy is taken as the objective function, design study is performed and some variable whose sensitivity are high are chosen to optimize the vibration isolation performance of power train mount system. And the result shows that the vibration is reduced effectively.
