It is found that the powertrain mount system of an engineering machine has a reasonable energy distribution, but its vibration isolation effect is not good. To solve the problem, the powertrain mount system is optimized with the energy decoupling and the minimum vibration transmission rate as the optimization objectives. The powertrain mount system is simulated by means of ADAMS software and some optimization parameters are obtained. Then, the vibration isolation test under different working conditions of the system is performed. Results of the analysis and test show that both the energy decoupling and the vibration isolation performance of the powertrain mount system are satisfactory after the optimization.
