摘　　要：研究的目的在于通过利用多孔管,膨胀腔的消声特性解决在满足基本消声性能前提下声品质不佳的问题,提升消声器的主观感受声品质,其对整车的乘员舒适性改进有较明显的效果,对消声手段的应用有现实的指导意义。通过具体的实例来说明消声元件的消声结构和能达到的消声效果之间的主客观数据对应关系,在解决排气噪声问题的同时能够尽量提升声品质并基于此改进思路设计合理的子零件结构提供了参考借鉴。The purpose of this study is to use the muffler property of the perforated pipe and the expansion chamber to resolve the problem of poor sound quality of the muffler, to improve driving comfort, and to guide the application of noise elimination measures.This article uses specific examples to explain the subjective and objective corresponding relations of the noise elimination structure and the noise elimination effect, and to offer reference for the design of part structure that can resolve the noise problem of the exhaust system and improve the sound quality at the same time.

关 键 词：排气系统 声品质 消声结构
