| Abstract: | Before the official series production, the car the noise inside the car will be strictly controlled. Finding the source of the noise is always a difficult job during NVH analysis. This article introduces the NVH analysis of the noise phenomenon generated by rotating devices, how to set the parameters of the analysis software, and the meaning of the main parameters in the analysis. Finally, the source of the noise is found based on the results of the order analysis. |
