摘要在涡扇航空发动机声衬表面，存在高速切向流场与高声强声场耦合问题，吸声机理与调控机制复杂。高切向流速高声强条件下低频宽带噪声的有效吸收极具挑战性。该研究提出考虑高切向流速、高声强以及复杂容抗修正的声阻抗理论方法，设计了梯度阻抗调控吸声超材料。从理论解析计算、有限元数值建模及试验测试三个维度深入分析声波与结构的作用机理和调控规律。结果表明：梯度阻抗吸声超材料可有效提高吸声效率，避免传统声衬吸声频带窄的缺点。在0m/s、30m/s、60m/s、98m/s切向流速和130dB背景噪声下，提出的梯度阻抗吸声超材料在500Hz-3000Hz范围内具备良好吸声效果。该超材料结构简单，在高切向流速高声强复杂边界条件下，仍有深亚波与宽带吸声特性，具有广阔的应用前景。

Abstract：There is a coupling problem between high-speed grazing flow field and high sound intensity sound field on the acoustic liner surface of turbofan aero engine, and the sound absorption mechanism and regulation mechanism are complex. The effective absorption of low-frequency broadband noise under the condition of high grazing velocity and high sound intensity is very challenging. In this paper, a theoretical method of acoustic impedance considering high grazing velocity, high sound intensity and complex capacitive reactance correction is proposed, and a gradient acoustic impedance controlled sound absorbing metamaterial is designed. The interaction mechanism between sound wave and structure and the regulation law of sound wave are deeply analyzed from three dimensions: theoretical analytical calculation, finite element numerical modeling and experimental verification. The results show that the gradient impedance sound absorbing metamaterial can effectively improve the sound absorption efficiency and avoid the disadvantage of the narrow sound absorption band of the traditional acoustic liner. Under the grazing velocity of 0m/s, 30m/s, 60m/s, 98m/s and 130dB background noise, the gradient impedance sound-absorbing metamaterial proposed in this paper has a good sound-absorbing effect in the range of 500Hz-3000Hz. The metamaterial has a simple structure and still has deep sub-wave and broadband sound absorption characteristics under the complex boundary conditions of high grazing velocity and high sound intensity.

Key words： acoustic liner gradient impedance regulation gradient curl cavity low frequency broadband sound absorption
