摘要：

A vibro-acoustic test to a prototype of fuel cell car in various operating conditions is taken on the four -wheel-drive chassis dynamometer in the semi-anechoic chamber. And we collect sound signal of the interior noise and the vibration signal of body panels and some parts radiating noise of the fuel cell car. Through analyzing the test data, the characteristics and sources-of interior noise are identified. The sound pressure level at the driver right ear position is always lower than the one of passenger right ear position, but the difference of the two noise decreases with vehicle's speed increase. The assembly unit of traction motor of the vehicle and the hydrogen-pump and fan of the fuel cell system are the main sources of interior noise, which partly due to the air-borne noise and partly to the structure-borne noise. The traction motor's contribution to the interior noise becomes more and more dominating with the vehicle's speed increase.
