Abstract
The lightweight design of electric vehicles (EVs) is studied. The characteristic of sound source distribution of the EVs is considered. At first, the lightweight design of key acoustic package components of EVs is studied. On the premise of ensuring the acoustic performance of the components, the Biot parameters of acoustic package materials are optimized by combining the test and simulation methods, and the weight of the key acoustic package components are reduced by 58%, and the target of the acoustic packet lightweight is reached. At the same time, influence of the uncertainties of thickness, material parameters (flow resistance, density) and so on in the manufacture and transportation process of the acoustic package components on the robustness performance of the whole vehicle acoustic package is studied. The results show that the lightweight acoustic package components with good robustness and sound performance can be designed by reasonable optimization analysis.关键词
