摘要

大尺寸有源微穿孔板吸声器的低频吸声性能依赖于入射声场环境, 故在现有管道声场的研究基础上, 探究了其在自由场环境中的有源吸声性能. 首先, 引入随位置变化的声压反射系数表征非局部反应表面在垂直入射平面波激励下的反射声场, 并结合模态分析法建立理论模型. 其次, 从空腔声模态对入射波的反射作用及对声吸收的贡献度揭示了自由场中有源吸声的物理机制, 构建了误差传感策略. 最后, 实验验证了理论模型与所获结论的正确性. 研究表明: 入射波激励起的(0, 0, 0)空腔声模态, 其幅值越大对入射波的反射作用越强; 控制源抑制该声模态并使其幅值降到最优值时, 它不再反射并会大幅吸收入射波, 低频吸声性能显著提升. 但控制源激发的高阶空腔声模态对入射波起完全反射作用, 将阻碍控制性能的提升. 故相比于管道声场, 自由场中的有源吸声性能有所减弱. 控制源在抑制(0, 0, 0)声模态的同时能确保不大幅激起高阶声模态时, 声压释放和阻抗匹配传感策略对自由场环境仍然适用.

Abstract

The active micro-perforated panel absorber has excellent low frequency sound absorption performance, which is expected to realize low-frequency noise reduction in large space of the cabin. Since its active sound absorption performance depends on the incident sound field environment, on the basis of the existing research conclusions in the duct, the active sound absorption performance of the large-sized active micro-perforated panel absorber under the excitation of a normal incident plane wave in typical free field environment is in depth investigated. First, the theoretical model of the active micro-perforated panel absorber is established by using the modal analysis approach, in which a reflection coefficient varying with position is introduced to represent the reflected sound wave on the surface of the active micro-perforated panel absorber in free field. Then, the physical mechanism of active control is thoroughly analyzed and the error sensing strategy is established. Finally, an experiment is carried out to validate the theoretical model and findings. Results obtained demonstrate that the greater the amplitude of the (0, 0, 0) cavity mode excited by the incident plane wave, the stronger the reflection effect on the incident sound wave is, and vice versa. The control source suppresses the (0, 0, 0) mode so that this mode will not reflect and absorb the incident plane wave substantially when its amplitude is reduced to an optimal value. This is main mechanism of the sound absorption improvement in the low frequency range. However, the excited high order cavity modes (except for (0, 0, 0) mode) greatly reflect the incident sound energy in free field and exert a negative effect on sound absorption improvement. Thus, the control performance of the active micro-perforated panel absorber weakens in free field in comparison with that in the duct. The pressure-release and impedance-matching strategies are still applicable to free field as long as such a situation holds, i.e. the (0, 0, 0) cavity mode can be substantially suppressed by the control source and at the same time the high order cavity modes cannot be highly excited.
