摘要
通过波束形成声源识别测试系统,对某电动汽车进行通过噪声的波束形成声源识别测试,确定不同速度工况下最大声源强度的位置及频率特性,为后续研究提供依据。
Through the beam forming sound source identification test system,this paper performs a test of beam forming sound source identification of passing noise of an electric vehicle,and determines the location and frequency characteristics of the maximum sound source intensity under different speed working conditions to provide a basis for the following research.
