摘要
根据经典旁路管消声器设计方法,建立柔性壁慢波速旁路管水动力噪声消声器的物理模型,分析旁路消声器材质、尺寸参数对水管路消声性能的影响,用实验验证了慢波速旁路管消声器的消声效果,并采用并联不同长度慢波速旁路管的方式在宽频域内达到较好的消声效果。
A physical model of low sound wave speed by-pass tube silencer with flexible wall is etablished on the basis of classical by-pass tube silencer design method. Through numerical simulation, the influence of parameters, such as material and size, on the sound transmission characteristics of silencer is investigated. That is also identificated by experiments. Connecting several low speed by-pass tubes with different sizes in parallel is adopted to get better sound attenuation in broder frequency band.
