Road Test Analysis for Interior Noise of Wheel-hub Motor Driven Micro Electric Vehicle
Identification of vibration source,transfer way and main contribution panels are conducted consider-ing the interior noise of four--wheel-hub motor driven vehicle based on road test.Measurement of interior noise and vibration signal is conducted in accelera-ting,regenerative braking and constant speed driving conditions.Combining time domain,frequency do-main and order spectral analysis,and the result shows that the major source of interior noise is the sixth harmonic vibration of wheel-hub motor.The in-fluence of every body panel in different frequency range is also presented,which has reference value for the development of wheel-hub motor driven electric vehicle.
