| Abstract: | The distribution of the rear interior noise of the fuel cell vehicle is realized according to the result of the sound pressure level test. The dominated frequencies of the noise are obtained through the frequency-spectrum analysis to the test data and the main sources of the noise are identified basing on the vibration test. After taking the measurement of noise insulated and absorbed the insulating noise performance of the rear squab panel and rear shelf are improved to the middle and high frequency band of the sound. In addition, the pressure and frequency character of the interior noise in the rear of the cab are improved and the ride comfort as well. |
