Transfer path analysis of fuel cell vehicle interior air-borne noise

摘要

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 paths were measured and calculated, and interior air-borne noise was synthesized with actual excitation data. The contribution of different paths is analyzed, and the main transfer path was identified, which would be useful for fuel cell vehicle noise reduction.
