ZHANG Zhongdong,WU Hongting,ZHOU Houchang
Abstract: Aiming at the problem that the existing calculation methods of isolation rate do not apply to pure electric buses, a testing and calculation method for the isolation performance of the powertrain suspension system applicable to pure electric buses is proposed based on the calculation method for the suspension isolation performance of traditional fuel power buses,which provides technical support for evaluating the sus-pension isolation performance of pure electric buses and the treatment and optimization of NVH problems caused by poor isolation performance.
Key words: pure electric bus; powertrain; suspension system; vibration isolation performance
