摘　　要：利用GT-Power软件建立了某排气消声器的仿真模型,并得到消声器的传递损失曲线。通过分析其消声特性,对消声器结构进行了局部改进。仿真结果表明,改进后消声器在中频段的消声性能得到明显提高。The simulation model of muffler is established by GT-Power software,and the transmission loss of the exhaust muffler are obtained.Local improvements on the muffler structure is conducted after analyzing the exhaust muffler feature. The simulation results show that the performance has been obviously improved under medium frequency.

关 键 词：排气消声器 传递损失 性能 结构改进
