Inerter-enhanced metastructure for structural vibration control

基于元的振动控制技术由于其特殊的滤波效果而被提出。然而，目前的技术很难对低频波进行衰减，因此不适合民用结构的振动控制。这个项目建议将基于交互的元素合并到元结构的单元格中。由于干涉元件独特的质量放大特性，使得对低频波的操纵成为可能。针对三种典型振源引起的工程结构的不良振动，提出并应用了实际设计方案。通过全面的分析、实验和数值研究来验证所提出方法的有效性。

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.
