摘要

薄膜-质量型声学超材料结构质量轻，低频段隔声性能优越，在船舶等领域的噪声控制上有着较好的应用前景。结合隔振原理和超材料简化模型从理论上解释了其在低频段优越隔声性能的产生机理，并在有限元模型中得到了验证。从基础构型出发，研究了质量块密度等结构参数对隔声性能的影响。提出了水平和垂向多胞元组合设计来提升隔声带隙宽度的新型超材料结构，通过数值仿真模型计算研究了组合设计下隔声带隙的叠加规律。结果表明，薄膜-质量型声学超材料的隔声性能受结构参数影响，超材料胞元的组合设计可以显著提升隔声带宽。本研究可以为声学超材料轻量化设计与隔声性能提升提供参考。

Abstract

The mass-attached membrane-type acoustic metamaterial is lightweight and exhibits excellent sound insulation performance in low frequency. For that reason, it has a good application prospect in noise control of ships and other fields. The generation mechanism of their excellent sound insulation performance in the low-frequency band is theoretically explained by the principles of vibration isolation and the simplified model of metamaterials. Also, this has been verified in a finite element model. Starting from the basic configuration, the influence of structural parameters such as the density of mass block on sound insulation performance is studied. A novel metamaterial structure with horizontal and vertical multi-cell combination design is proposed to enhance the width of the sound insulation bandgap. Numerical simulation models were used to study the superposition law of sound insulation bandgaps under this combined design. The results indicate that the sound insulation performance of that acoustic metamaterials is affected by structural parameters. The combined design of metamaterial cells can significantly improve the sound insulation bandwidth. This study provides a reference for lightweight design and sound insulation performance enhancement of acoustic metamaterials.
