Abstract

Based on energy decoupling theory, an optimization on the powertrain mounting system of a bus is conducted with genetic algorithm, and the rule of the effects of non-proportional damping and gyroscopic effect on vibration decoupling is studied for optimized mounting system. The results show that non-proportional damping has significant influence on the vibration characteristics of system, which mainly aggravate the coupling between translational and rotational vibrations. Its effect is getting more sever with the rise in the degree of non-proportional damping. The effects of gyro moment are mainly on the pitch and yaw responses of powertain and the intensification of vibration coupling between them in low frequency range.
