摘　　要：利用形状记忆合金(SMA)的超弹性特性,将SMA丝与摩擦阻尼器复合,提出了一种SMA复合摩擦阻尼器,给出了SMA复合摩擦阻尼器的工作机理和设计方法,建立了其理论模型,确定了SMA复合摩擦阻尼器的力-位移滞回曲线,并对一SMA复合摩擦阻尼器控震单自由度体系在地震作用下的动力响应进行了数值模拟。结果表明,提出的SMA复合摩擦阻尼器具有优良的耗能减振性能。Based on the superelasticity of shape memory alloy （SMA）, a vibration-mitigation device, known as SMA incorporated friction damper is developed by combining the SMA wires with the friction damper. The design procedures and working mechanisms of the SMA incorporated friction damper are presented in this paper first. Then, a theoretical model of the developed damper is established. According to this theoretical model, the forcedisplacement hysteretic loops of the damper are obtained. Finally, dynamic responses of a SMA incorporated friction damper controlled SDOF system under earthquake action are simulated. The numerical results show that the proposed damper device has excellent energy dissipation capacity.
