Optimization of Sound Package for Automotive Dash Panel

Abstract:

The design of automotive trim configurations has become increasingly driven to maximize the acoustic performance benefit while minimizing material weight. Statistical energy analysis (SEA) can serve as a useful tool to predict the high frequency acoustic response on both a component and full vehicle level. This paper focuses on the automotive dash panel, using VAOne software to establish the SEA model. The method of orthogonal test is applied to optimize the sound package design to satisfy maximum high-frequency transmission loss (TL) and minimum weight by modifying the acoustic material, thickness, surface density and coverage of sound package.
