Experimental Study on NVH Performance of Midi Pure Electric Vehicle

Abstract:

Measurement of interior noise and vibration signals were conducted in accelerating and constant velocity driving conditions. By using time domain, frequency domain and 3D spectral array methods, the exterior noise, interior noise, the vibration acceleration of driver’s seat and suspension, the NVH characteristics of the Midi EU vehicle were analyzed. On the one hand, we find that the interior noise is larger than exterior noise under accelerating state, due to the cabin poorly sealing. On the other hand, because of the poor isolation rate of the driver’s seat, the vibration acceleration on the driver’s seat is very great and affecting the driver’s comfort. The experimental results also shows that the isolation rate of the suspension are relative good under different velocities. These experimental results will give help to further study of the NVH characteristic of the pure electrical vehicle.
