摘　　要：基于SYSNOISE FEM-Fluid分析方法,分别对无插入管扩张室消声器、单插入管扩张室消声器和双插入管扩张室消声器的传递损失进行仿真模拟,从而得到不同结构不同穿孔率消声器的传递损失曲线。通过对传递损失曲线的分析,比较了不同结构的传递损失并且提出了具有较好消声效果的消声器结构。Based on a Fluid-FEM method named SYSNOISE, and simulations of transmission loss with non-insertion tube expansion chamber muffler, single insertion tube expansion chamber muffler and dual insertion tube expansion chamber muffler are done, then transmission loss curve in different structures of different perforation muffler is obtained. Through analysis and comparison of the different structures of the transmission loss curves, a good effect muffler structure is proposed.
