| Abstract: | Expansion Mufflers which have a good acoustic attenuation performance.simple structure.low cost and so on, are widely used in internal combustion engines intake and exhaust noise controls. In order to in-depth understanding of it＇s acoustic attenuation performance, this paper discusses the effect of the structural parameters on the basis of finite element method. |
