摘　　要：文章通过了解常见的增压器噪声产生的机理,对开发中某汽车存在的NVH问题进行研究,明确噪声来源,并通过对进气系统进行优化设计,主要是增加谐振腔和高频消音器来降低显著噪声,最终达到了整车降噪要求,改善了整车NVH性能,提高产品竞争力。By understanding the mechanism of common noise generated by the supercharger,this article researches the NVHissue of a vehicle under development and insures the origin of the noise.The intake system has been optimized by increasingresonator and high frequency muffler to reduce the apparent noise.Ultimately achieves the vehicle noise reductionrequirements,improves vehicle NVH performance,improves product competitiveness.

关 键 词：增压器噪声 谐振腔 高频消音器
