摘要
车内的结构传播噪声的来源,除了发动机激励外,与路面相互作用的轮胎也是主要激励源之一。本文通过一个车内Booming噪声改善的工程案例,给出了一种车内低频噪声源的识别方法,并通过理论计算分析了相关因素的影响,为该噪声的治理提共了数据依据和改善方向,最后对改善方案进行了试验验证,得到了令人满意的效果。
The vehicle interior noise has two main sources,the engine and the rolling tire interacting with the road surface.In this paper a vehicle booming noise improvement case is presented,a low frequency noise source detection and improvement method is proposed,and the improved effect is validated through the measurement.
