Optimization of Installation Form of Battery Pack Based on Acoustic Sensitivity Analysis

The main content of this paper is to explain that the acoustic sensitivity of the trimmed body of the vehicle can be improved by optimizing the installation form of battery pack, and then the interior noise of the whole vehicle can be reduced. Firstly, based on the acoustic sensitivity theory and simulation analysis method, the analysis model of the trimmed body with battery pack structure is established, and the acoustic sensitivity of the key connection points of the trimmed body is simulated and analyzed. Secondly, the acoustic sensitivity of the trimmed body is effectively improved by optimizing the installation form of the battery pack and the structure of the battery pack bracket. Finally, the improved scheme is verified and tested on the real vehicle road, and the expected experimental results are obtained.
