惯容减震(振)系统及其研究进展

惯容是一种两端点加速度相关型新型结构控制元件。惯容减震（振）系统是包含惯容元件的结构振动控制系统。该文整理并总结了国内外学者在惯容及惯容减震（振）系统方面取得的大量研究成果，从惯容的实现机理、惯容减震（振）系统性能、惯容减震（振）结构体系的分析设计三个方面介绍、论述惯容的原理及其在减震（振）控制领域的发展历程与研究现状。相比于传统减震（振）系统，惯容减震（振）系统具有如下优势：能够实现惯性的灵活调整和频率的调节、改变结构惯性同时基本不改变结构的物理质量、提高惯容系统中消能器的耗能效率。该文旨在梳理惯容减震（振）系统的发展脉络与现状，为惯容减震（振）系统在结构振动控制中的应用提供理论依据和设计参考，以推进惯容减震（振）系统理论与实践的持续发展。

INERTER SYSTEM AND ITS STATE-OF-THE-ART

An inerter is a two-terminal acceleration-dependent mechanical element for structure control systems.The inerter system is an integrated system for the structural vibration control with inerters.A large number of studies and research projects on the inerter systems have been comprehensively reviewed in this paper.The state-of-the-art of inerter systems in the field of structural vibration control system were discussed from the following three aspects:realization of the inerter mechanism;performance of the inerter system and design of the structures with inerter system.Compared with traditional vibration control systems,the inerter system has its advantages including:the inertia of the structure can be adjusted and the tuning can be achieved flexibly;additional physical mass is negligible when the inertia of the structure changes obviously;the efficiency of energy dissipation is enhanced.This review paper is intended to provide theoretical evidence and practical guidance for the design,application and further development of inerter systems.
