摘要
为了增加固定体积消声器的传递损失,以穿孔管消声器为例,利用GT-Power软件建立消声器三维实体模型,并进行仿真模拟,计算消声器传递损失。通过对比不同布置间距双穿孔管消声器的传递损失,得到双穿孔管消声器传递损失叠加规律,为双穿孔管消声器设计提供了理论依据。
In order to increase transmission-loss in muffler of certain chamber the perforated muffler is studied. Based on GT-Power software the 3-D model of the mumer is developed, and the transmission-loss in it is calculated. After transmission-loss in the double perforated muffler in which distance between two pipes is different is calculated, the rules of transmission-loss in the double perforated muffler are obtained, and the theory principle of the design for double perforated muffler is also presented.
