摘要

摘要: 为了研究某飞机飞行中因登机门修型而产生的强烈啸叫问题，结合机身表面流动特征和登机门缝腔体的实际构型，建立符合实际流动特征的二维不规则腔体模型，采用脱体涡模拟结合Ffowcs Williams-Hawkings积分方程的混合方法对两种类型的登机门带肩壁腔体进行流动和噪声特性的数值模拟，分析了登机门缝纯音噪声的产生机理。结果表明：对于单肩壁门缝腔体，长深比的增大使得腔体内旋涡之间相互作用加剧、腔内压力脉动更加剧烈，远场总声压级平均增大3~10 dB，表明门缝腔体的长深比对噪声水平有明显的影响。建立的某飞机登机门缝不规则二维腔体模型符合物理实际，数值计算得到的纯音频率基本落于试飞测试得到的纯音频率区间内，能够反映该飞机登机门啸叫噪声的主要物理特征。

Abstract: In order to study the strong howling problem caused by the modification of the boarding gate of an air-plane in flight，a two-dimensional irregular cavity model was established according to the actual flow characteristics by combining the flow characteristics of the fuselage surface and the actual configuration of the boarding gate seam cavity.The flow and noise characteristics of two types of boarding gate seam cavities with shoulder wall were numerically simulated by using the hybrid method of detached-eddy simulation and Ffowcs Williams-Hawkings integral equation，and the generation mechanism of pure tone noise at the boarding gate seam was analyzed.The results show that for the seam cavity with single shoulder wall，the increase of the length-depth ratio makes the interaction between vortices in the cavity intensify，and the pressure pulsation in the cavity becomes more intense，as well the total sound pressure level in the far-field increases by 3~10 dB on average，which indicates that the length-depth ratio of the cavity has obvious influence on the noise level.The irregular two-dimensional cavity model of an air-plane gate seam established accords with the physical reality，and the pure tone frequency by numerical calculation basically falls within the pure tone frequency range obtained by flight test，which can reflect the main physical characteristics of the airplane boarding gate howling noise.
