【摘要】 介绍了形状记忆合金(shape memory alloy,简称SMA)的主要特性,建立了SMA阻尼器的热力学平衡方程,并通过实验分析了SMA阻尼参数对结构风振控制效果的影响,结果表明:在相同屈服阻尼力下,随刚度比的增大和屈服位移比的减小,SMA阻尼器的减振效果增加。更多还原

【Abstract】 It is introduced the shape memory alloy’s principal characteristic,and a constitutive relation is set up.It is analyzed the influence of SMA attenuator parameter to the control effects of structural wind-induces vibration through an experiment.The results indicate that under same yield damping force,with the increasing of the rigidity ratio and the reducing of yield displacement ratio,the control effects of SMA attenuator will be increased.更多还原
