Abstract
This paper presents the results of Noise Vibration and Harshness (NVH) study based on the Source-Transfer-Receiver Model in Fuel Cell Vehicle (FCV) [1]. Above all, vibro-acoustic testing of FCV was conducted, and through signal analyzing the main noise and vibration sources were identified to be the regenerative fan and air filter, component parts of the air auxiliary system. Then Transfer Path Analysis technique was applied to identify the main transfer paths from noise and vibration sources to the interior of the vehicle, to measure transfer functions linking source locations to target locations and to estimate the internal vibro-acoustic comfort in operating conditions. Finally feasible noise and vibration reduction measures were proposed based on the vibro-acoustic characteristics of the FCV discussed above.
