非对称双层薄膜型局域共振声子晶体低频隔声性能研究
|
摘要
薄膜型局域共振声子晶体结构简单、既薄又轻,是理想的低频隔声材料。对非对称结构双层薄膜型局域共振声子晶体材料的声学低频隔声性能进行研究,讨论声子晶体非对称结构中质量块分布方式、位置以及数目对声学衰减特性的影响。研究表明非对称结构双层薄膜型声子晶体由于其结构的非对称能够在低频呈现出优异的轻质、宽频隔声特性,且可通过调节质量块在薄膜上的位置、质量块的数量及分布方式对声波隔声的频率位置进行调节。
Membrane-type local resonant acoustic metamaterial is an ideal low-frequency sound insulation material for its simple structure and lightweight. In this paper, the low-frequency sound insulation performance of the asymmetric doublemembrane type acoustic metamaterial is studied. The influences of the distribution and number of the attached mass blocks in the asymmetric structure on the acoustic attenuation characteristics are discussed. The results demonstrate that this metamaterial has the characteristic of lightweight and good sound isolation performance in a wide low-frequency range due to its asymmetrical structure. The frequency of sound insulation can be tuned by adjusting the position, the number or the distribution form of the mass blocks on the membrane.
