摘要
利用软件GT-Power仿真并联内插管双室扩张式消声器,得到其插入损失变化情况。通过仿真结果跟实验数据的比较表明,GT-Power仿真结果在较宽频带范围内具有良好的拟合度,符合实际的。GT-Power仿真消声器的插入损失是准确而有效的。
The muffler with parallel of expansionary insert-pipe inside of two rooms is simulated on the software GT-Power, which can get the status of the insert loss. The comparison of the simulation results and the experimental data shows that it is a good fitness in the wide frequency channel and it is in the fact. It is exact and effective in the muffer＇s insert loss simulation.
