【Abstract】 The software ADAMS is used to set up a six-degree dynamic model of power train mount system.According to the characteristics of vibration isolation performance of power train mount system and by using the method of parametric model and the algorithm of Gradient Method,the optimum design of power train mount system is made with the minimum amplitude of response force as the objective function at idle mode of engine.The vibration brought by the second order reciprocating torque of the engine is reduced effectively.更多还原
