摘要
根据客车车内噪声产生的机理和传播途径,介绍车内噪声控制策略;通过噪声试验,对客车主要的噪声源、噪声辐射部位进行改进控制,并通过改进车身隔音降噪结构,达到降噪目标。
According to the mechanism of coach interior noise and its transmission routes, the authors introduce the control strategies of coach interior noise. Through the noise test, they improve the control of main noise sources and noise radiation parts of the coach, and through improving the body structure of sound insulation and noise reduction, they finally achieve the noise reduction targets.
