Abstract

In this paper, we based on a bench test and analyzed the noise characteristic of the centrifugal blower in the air auxiliary system of a fuel cell vehicle. By the noise prediction, a test scheme was designed clearly. In the test, the vibration and noise signal under different operational states has been measured. It was obvious that the main noise of the centrifugal blower was consist of the order noise and the broadband noise. Through the spectral analysis and order analysis, it is identified that the inlet noise, aerodynamic noise of the drive motor and the blower wheel are the main noise sources of the centrifugal blower.
