摘要
针对某MPV车型低转速下排气系统引起的车内轰鸣声,分析和探讨了排气系统噪声对车内噪声产生影响的原因及解决路径,并通过软件GT-POWER,对排气系统消声器内部结构进行了优化,降低了低转速下车内轰鸣声。其研究结果为后续车型排气结构设计和目标设定提供了指导。
The problem of interior booming noise in low speed is proposed on, which iscaused by exhaust system.The reason of how exhaust system noise impacted on interiornoise was studied.The methods to solve this problem was discussed. GT-POWER to op-timize muffler interior structure is used to reduce interior booming nosome guidance for subsequent vehicles exhaust structure design.
