摘要

开发声学超材料的一个挑战是同时考虑宽带屏蔽和承载能力的应用。本文提出了一种基于蜂窝的分级AMMμsuuer，通过集成设计，可以在没有任何外部装置的情况下拓宽衰减带，提高结构的稳定性。首先，从理论上和数值上研究了mu solu-er晶胞的声学和力学特性，并根据这些特性设计了分级mu solu er。数值结果表明，分级的μ松露使晶胞的衰减带宽变宽，模拟结果还表明，分级μ松露比均匀μ松露具有更大的sti。sti effness驱动的μsuuer为设计同时具有隔音和承载性能的先进超材料提供了新的可能性。

A Honeycomb Based Graded Metamaterial Muffler with Broadband Sound Attenuation and Load Bearing Performances

A challenge for developing acoustic metamaterials (AMMs) is considering the application of broadband muﬄing and load bearing capacity simultaneously. In this paper, a honeycomb based graded AMM muﬄer is proposed, which can widen the attenuation band and improve the structural stiﬀness without any external device by means of integrated design. Firstly, the acoustic and mechanical characteristics of the muﬄer unit cell are theoretically and numerically studied, and the graded muﬄer is designed based on these characteristics. The numerical results show that the graded muﬄer widens the attenuation bandwidth of the unit cell, and the simulation also shows that the graded muﬄer has greater stiﬀness than the uniform one. The stiﬀness driven muﬄer provides new possibilities for the design of advanced metamaterial with simultaneous sound insulation and load bearing performances.
