摘要 扩张式消声器具有结构简单﹑成本低廉﹑消声性能良好等优点,广泛应用于汽车进排气系统噪声控制,为对其消声性能进行深入分析,应用有限元数值仿真方法,详细讨论了结构参数对消声性能的影响。 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.
