Construction of acoustic model and simulation of sound absorption of aero-engine composite acoustic liner

  • 摘要: 声衬是降低发动机噪声的重要组件。本工作计算不同流场状态下管道模态声源特征,并以此作为Actran软件背景流场计算及声传播计算的输入边界,建立声传播模型,研究单自由度声衬与双自由度声衬消音板孔直径、孔间距、蜂窝高度和消音板厚度4种结构参数对吸声效果的影响规律。仿真结果表明:两种自由度声衬都表现出在一定孔直径范围内穿孔直径越小,吸声性能越好的现象;孔间距、蜂窝高度和消音板厚度对吸声性能的影响随频率变化;在2500 Hz以上双自由度声衬耗散功率较大,吸声效果好。通过在流管实验对比验证,比较不同结构声衬在不同激励源下的传递损失,得到合理可信的仿真方法。
