Based on the experimental analysis of vibro-acoustic test of the fuel cell vehicle (FCV) while hydrogen-supply system operating independently, it is the improper structure of the hydrogen pump cabinet in power auxiliary system that led to noise emissions both in and out of the vehicle. Modal test and finite element (FE) modal analysis were carried out to verify the sympathetic vibration frequency...
Taking fuel cell vehicle as an example, this paper carried out interior noise transfer path analysis. The application of the traditional method of transfer path analysis, the acoustic reciprocity law, proposed path contribution calculation method under single-frequency and the main frequency band. Through transfer path test of interior noise of fuel cell vehicle, acoustic transfer functions of different...
