Inerter-enhanced metastructure for structural vibration control

基于元的振动控制技术因其特殊的滤波效果而被提出。然而，现有的技术难以衰减低频波，因此不适合民用结构振动控制。这个项目提出将一个基于惰性元素的元结构单元。由于惯性元件独特的质量放大特性，操纵低频波成为可能。针对三种典型振源引起的工程结构不利振动，提出了实用的控制设计方案。综合分析，实验和数值研究进行了检查所提出的方法的有效性。

Meta-based technique has been proposed for vibration control recently due to its special wave filtering effect. However, the current techniques are difficult to attenuate low-frequency waves, thus not suitable for civil structural vibration control. This project proposes incorporating an inerter-based element into the unit cell of a metastructure. Due to the unique mass amplification characteristic of inerter element, manipulating low-frequency waves becomes possible. Practical designs are developed and applied to control the adverse vibrations of engineering structures induced by three typical vibration sources. Comprehensive analytical, experimental and numerical studies are carried out to examine the effectiveness of the proposed method.
