Vibration control is extremely important for countless mechanical systems. Inerter is a two-terminal dynamic element proposed in 2002, based on analogy between mechanical system and electric system. Dynamic characteristic of an ideal inerter is pure inertia. Force applied on each terminal of an inerter is directly proportional to relative acceleration of two terminals. Since inerter was put forward, it has made significant progress in vibration control systems. The paper is a review about physical realizations of inerter as well as inerter-based vibration control. Physical realizations and applications in vibration control of inerter are focused. First, the develop of inerter and typical physical realizations of inerter are introduced. The normative derivation processes based on Lagrange equation method of the dynamic relationships in the different inerters are summarized. And then, three categories of common inerter-based vibration control systems are explained. Finally, research trend of physical realizations of inerter are summarized, and the possible researches on inerter-based vibration control are discussed.
振动控制对于无数机械系统而言极其重要。惯容是2002年提出的一种二端动态元件，它基于机械系统与电气系统之间的类比。理想惯容的动态特性是纯惯性。施加在惯容每个端子上的力与两个端子的相对加速度成正比。自惯容被提出以来，它在振动控制系统中取得了显著进展。本文是关于惯容的物理实现以及基于惯容的振动控制的综述。重点关注惯容的物理实现及其在振动控制中的应用。首先，介绍了惯容的发展历程以及惯容的典型物理实现方式。总结了基于拉格朗日方程法对不同惯容中动态关系的规范推导过程。然后，阐述了三类常见的基于惯容的振动控制系统。最后，总结了惯容物理实现的研究趋势，并讨论了基于惯容的振动控制可能的研究方向。
