摘　　要：提出了形状记忆合金材料的相变超弹性恢复力模型，并以此为基础对形状记忆合金减振控制系统的动力响应进行了数值模拟分析。结果表明，这种减振控制装置对较强烈的振动有更好的抑制作用，因此可在建筑结构的抗震控制中发挥其独特的作用。Two hysteric models are presented here to describe the relationship of transformation super-elastic restoring force and deformation of shape memory alloy(SMA)materials,basing on which the dynamic response of the vibration absorbing system of SMA is investigated by means of numeric simulation.The results obtained in the paper show that this kind of the control system has better restraining effect over more heavily excited vibration that ordinary linear one.Therefore,such system can play a specific role in aseismic control of buildings.
