摘要
开状记忆合金是一类应用前景广阔的智能材料系统，利用形状记忆合金材料控制结构振动是最能体现这种先进材料应用价值的重要研究方向之一．本文首先介绍形状记忆合金的主要力学行为，包括形状记忆效应和超弹性效应；其次概述描述其力学行为的本构关系模型；最后重点论述实现结构主被动控制的原理和方法及其国内外研究进展，指出存在的问题和改进方法．
Shape Memory Alloy (SMA) is one class of intelligent material system which has shown broad application area. Vibration control of structures using SMA material is one of important research direction which is well-shown applicable value of this advanced material. In this paper, a brief introduction of the main mechanical behavior of SMA including the shape memory effect and superelasticity is presented at first. The constitutive equations ultilized in describing the mechanical behavior of SMA are also reviewed. The focus of this investigation is on the principles and approaches for active and passive vibration control of structures and the recent development both in China and abroad. Finally, problems and future studies are discussed.
