Experimental Study on Vibration of Pure Electric Bus

Abstract:

Measurement of vibration signals were conducted in accelerating and constant velocity travelling conditions. By using time domain, frequency domain and 3D spectral array methods, the vibration acceleration of passenger’s seat, power assembly and suspension, the NVH characteristics of the pure electric bus were analyzed. On the one hand, we find that the vibration level of passenger’s seat increase linearly with the travelling speeds. On the other hand, because of the poor isolation rate of the power assembly mount and the chassis suspension, the vibration acceleration on the passengers’ seats are very great and affecting the passengers’ comfort. These experimental results will give help to further study of the NVH characteristic of the pure electrical bus.
