摘　　要：声学超构材料是由阵列化的人工微结构单元构筑的复合声学材料/结构。通过对声学超构材料中的微结构单元及其排布方式进行调控设计,可以实现对声波/弹性波(可视为固体中的声波)的人为高效操控,使其表现出超常的减振降噪性能及优势。当前,声学超构材料研究已成为机械工程、声学、力学、材料学、物理学等多学科交叉领域关注的热点方向。针对机械工程领域关注的装备振动与噪声控制技术背景,重点综述面向减振降噪应用的声学超构材料研究进展,分别从减振、隔声、吸声等功能应用需求出发,回顾国内外相关声学超构材料的研究进展,并指出当前研究不足,展望未来发展趋势,为推动声学超构材料在减振降噪领域的应用提供借鉴和参考。Acoustic metamaterials are composite acoustic materials/structures constructed by arrays of artificial microstructure units.By designing the microstructure units and their arrangement in acoustic metamaterials,it is possible to efficiently manipulate acoustic waves and elastic waves that can be regarded as acoustic waves in solids,and achieve extraordinary vibration and noise reduction performance and advantages.Currently,the study on acoustic metamaterials has become a hot topic in the interdisciplinary fields of mechanical engineering,acoustics,mechanics,materials science,and physics.Focusing on the background of vibration and noise control technology in the field of mechanical engineering,the research progress of acoustic metamaterials for vibration reduction and noise reduction applications is reviewed.Starting from the functional application requirements of low-frequency vibration reduction,sound insulation,and sound absorption,it provides a survey of the recent studies of acoustic metamaterials,points out the current research shortcomings,and looks forward to future development trends.The review can provide reference and guidance for promoting the application of acoustic metamaterials in the field of vibration and noise reduction.
