  • 针对低频噪声的隔离问题, 设计了一种基于压电材料的可调控薄膜声学超材料, 该材料由压电质量块嵌入弹性薄膜制成. 建立了材料的有限元分析模型, 并且计算了材料的各阶特征频率与20—1200 Hz频段的传输损失曲线, 并通过实验验证了有限元计算的真实性. 计算结果表明: 此声学超材料在20—1200 Hz频段内隔声性能良好, 存在两个50 dB以上的隔声峰与一个可调式的隔声峰. 通过分析简单结构的首阶共振模态并构建其等效模型, 从理论上探究了结构参数对薄膜声学超材料隔声性能的影响, 并通过有限元计算验证了其等效模型的正确性; 综合分析材料的特征频率与传输损失曲线, 进一步讨论了结构的隔声机理, 分析结果表明, 在特征频率处, 薄膜的“拍动”会导致声波在其后的传播过程中干涉相消, 实现声波的衰减; 通过Fano共振理论, 探究了各共振点处传输损失曲线特征不同的原因; 压电质量块与外接电路组成LC振荡电路, 在电路的共振频率处, 压电材料的振动可以吸收声波的能量从而造成一个隔声峰, 同时可以改变外接电路的参数来调整电路的共振频率, 从而实现对隔声性能的调控. 最后, 探究了压电质量块偏心量对材料性能的影响, 并通过有限元计算验证了材料隔声性能的可调性. 研究结果为可调式薄膜声学超材料的设计提供了理论参考.
    Aiming at the isolation of low-frequency sound, a kind of thin-film acoustic metamaterialis designed and obtained by implanting PZT into thin film. The finite element method (FEM) of the structure is built, and 1st–14th order eigenfrequencies and transmission loss between 20–1200 Hz are calculated. The reliability of finite element calculation is verified experimentally and the existence of adjustable sound insulation peak is monitored in the experiment. The results show that the acoustic metamaterial has good sound insulation performance in a frequency range between 20 and 1200 Hz, and has two sound insulation peaks of more than 50 dB, and there is a sound insulation peak which can be changed by adjusting the parameters of the outer circuit. By analyzing the first resonance mode of simple structure and building its equivalent model, the effect of structural parameter on the sound insulation performance of thin film acoustic metamaterial is investigated theoretically, and the rationality of the equivalent model is verified by the finite element calculation. The sound insulation mechanism of the structure is further illustrated by taking into consideration the eigenfrequencies, transmission loss curve and vibration mode diagrams at various frequencies. It is found that at the resonance frequency, the flapping motion of the film will cause the sound wave in the subsequent propagation to cancell the interference, therefore realizing the attenuation of the sound wave. Based on Fano resonance theory, the reasons for the different characteristics of transmission loss curves at different resonance points are investigated. The PZT and outer circuit can form a LC oscillator. At the resonant frequency of the oscillator, the vibration of the piezoelectric material can absorb the energy of sound wave to cause a sound insolation peak. The resonant frequency of the circuit can be adjusted by changing the parameters of the outer circuit, thereby realizing the adjustability of the sound insulation performance. The influence of eccentricity of piezoelectric mass block on sound insulation performance of material is explored, proving that the sound insulation performance can be further optimized by improving structure. And through the finite element calculation, it is proved that the sound insulation performance of material is adjustable by changing the parameters of the outer circuit. The results provide a theoretical reference for designing the thin film acoustic metamaterials.
