Optimization of Powertrain Mounting System of a Light Bus
TAO Deling,WANG Yixin
Abstract: Aiming at the NVH problem of a light bus,this paper takes the maximal energy decoupling rate of the suspension system as the target to find the optimal combination of available suspension schemes and validates them on the real vehicle. The results show that the vibration isolation performance of the optimized sus-pension is improved,and the vehicle NVH performance is significantly advanced.
Key words: light bus;mounting system;decoupling rate;NVH performance
