摘要

针对传统局域共振弹性超材料存在禁带宽度窄的问题

引入非均匀分布振子设计方法

在不改变振子总质量的前提下实现了禁带拓宽。首先

采用谱元法(SEM)建立通用弹性超材料梁模型

对单、双层均匀振子超材料梁结构的振动传递特性进行分析; 然后

保持振子总质量相等

提出单、双层非均匀振子超材料梁的设计策略; 最后

搭建实验装置对所提结构的振动抑制性能进行测试。研究结果表明:振子间的特征频率差异越大

最终形成的禁带宽度越宽

但禁带范围内的频响曲线会大幅波动

此时可通过加入适当阻尼进行抑制

使禁带曲线变得平稳; 对于双振子超材料梁

振子的质量比和阻尼均会对结构的禁带特性产生影响

在振子与梁质量相同的条件下

单层非均匀及均匀振子超材料梁可分别形成带宽为440、68 Hz的禁带

双层非均匀及均匀振子超材料梁可分别形成带宽为395、40 Hz的禁带。研究表明所提超材料结构能够有效实现振动抑制

可为周期结构的振动问题提供一种新的调控方法。

Abstract

To address the issue of narrow band gap width in traditional local resonance elastic metamaterials

a design approach is introduced that employs non-uniformly distributed resonators to widen the band gap without modifying the total mass of the resonators. Firstly

a generalized elastic metamaterial beam model is established using the spectral element method(SEM)

and the vibration transmission characteristics of both single-and double-layer metamaterial beams with uniform resonators are analyzed. Subsequently

a design strategy for single-and double-layer metamaterial beams with non-uniform resonators is proposed while maintaining a constant total mass of the resonators. Finally

an experimental setup is devised to evaluate the vibration suppression performance of the proposed structures. The findings indicate that a wider band gap is achieved when there is a greater difference in eigenfrequencies between the resonators. However

the frequency response curve within the band gap range may exhibit significant fluctuations

which can be mitigated by introducing appropriate damping to stabilize the band gap curve. The band gap properties of the structure in double-layer metamaterial beams are influenced by both the mass ratio and damping of the resonators. Under the condition of equal mass between the resonators and the beam

the single-layer metamaterial beam with non-uniform and uniform resonators exhibits band gaps with widths of 440 Hz and 68 Hz

respectively. Similarly

the double-layer metamaterial beam with non-uniform and uniform resonators displays band gaps with widths of 395 Hz and 40 Hz

respectively. The study demonstrates that the proposed metamaterial structures effectively achieve vibration suppression

providing a novel approach to address vibration-related challenges in periodic structures.
