【摘要】 形状记忆合金(SMA)是一种全新的功能性材料,介绍了形状记忆合金的主要特性,建立了形状记忆合金(SMA)阻尼器的热力学平衡方程,阐述了该种阻尼器在结构振动控制中的应用,并通过实验分析了形状记忆合金阻尼器参数对结构非线性地震反应控制效果的影响,分析表明:在相同屈服阻尼力下,随刚度比K增大和屈服位移比λ减小,SMA阻尼器的减振效果增加。更多还原

【Abstract】 The Shape Memory Alloy(SMA) is a kind of material possessing the brand-new functions.This article introduces the Shape Memory Alloy principal characteristic,establishes the constitutive relation,elaborates the Shape Memory Alloy application in the structure vibration control,and analyzes the influence of Shape Memory Alloy attenuator parameter to the control effects of structure non-linear seismic response through an experiment.The effects indicate: Under the same submits damping force,with the increasing of the rigidity ratio K and the reducing of submits displacement ratioλ,the shock absorption effects of SMA attenuator will increase.更多还原
