【摘要】 利用形状记忆合金(SMA)的超弹性滞回耗能特性,设计了一种新型的SMA阻尼器,以单层框架结构为模型,将该SMA阻尼器安装到结构的不同位置,通过大型有限元软件ANSYS进行模拟分析,比较了SMA阻尼器在不同位置时的减震效果。分析结果证明,安装本文设计的新型SMA阻尼器可以有效地减小结构的地震反应,为SMA阻尼器被动控制系统在结构抗震中的实际应用和设计提供借鉴。更多还原

【Abstract】 Shape memory alloy( SMA) has super-elastic hysteresis behavior. Recognizing this,a new type SMA damper is proposed.The single-story frame structure is used as the model. The SMA dampers are installed in different positions of the structure. Through the large-scale finite element software ANSYS,the seismic mitigation effects of which the damper installed in different position simulation are compared. The analysis result proves that the new type damper designed by this paper is effective to reduce the earthquake responses of the structure. The reference of application and design in SMA damper passive control system using in structure seismic is provided.更多还原
