| Abstract: | A three-dimensional dynamic model of the powertrain mounting system of a car made in China is set up. The effects of mounting parameters on the vibration isolation performance are investigated using parameter analysis method. In the optimization design of the powertrain mounting system,the mounting parameters are used as variables and both the rational disposition of intrinsic frequency and the minimum transmitting rate of vibration as the objective functions. The vibration of the car under its idle working condition is reduced effectively,and an experiment is made on a real car for verification. |
