摘要
基于管道无气流和平面声波传播模式建立了HQ管反声消声器传声损失的数学模型,并对单HQ管、串联HQ管及具有微穿、阻性材料内衬复合HQ管消声器进行了仿真计算和实验研究;依据分析研究结果,还探索了HQ管消声器的工程应用问题。
Based upon propagation model of in-plane sound wave without air flow,the numerical simulation & experimental study for single HQ tube,HQ tubes in series and compound HQ tubes with micro-perforated structure,sound absorption liner have been accomplished in this paper.The results show that simulation data provided by the transmission loss models for HQ tubes are good agreement with experimental data.Compound HQ tubes,suitable for industrial applications,are discussed in this paper aiming at the broad-band exhaust noise.
