关于电动车真空泵噪声来源及优化方案

Noise Mechanism and Reduction of Electric Vehicle Vacuum Pump

电动车因为前舱无传统燃油动力总成,故真空泵的噪音比燃油车更清晰。文章从分析真空泵噪声产生的来源、噪声的传播路径方面、噪声优化方案等方面分析,通过测试不同降噪方案在整车上实际应用后的降噪效果,寻求最佳优化方案。

Compared with the fule vehicle,Electric vehicle without engine,The same noise in the electric vehicle ockpit can be easier identified.This paper analyses the causes of vacuum pump noise source、travel path and suggestions for improvement,Contrastive analysis sound test of different noise improvement plans seek preferred plan,Realize electric vehicle noise minimum.
