摘要
基于现有形状记忆合金阻尼器的优点提出了一种新型形状记忆合金阻尼器,描述了它的工作原理并给出了具体构造,适当确定框架结构安装此种阻尼器的数量,用时程分析的方法比较了安装和未安装此种阻尼器的减振效果,说明了形状记忆合金在结构振动控制方面的有效性与适用性.
This paper introduces one of constitutive relationship of Shape Memory Alloy (SMA). According to the advantage of various SMA dampers, a new SMA damper is developed. The proposed damper is characterized by good energy dissipation mechanism , and constructional detail of the damper is presented. Based on the time-history emulation analysis for frame, two results with SMA dampers and without SMA dampers are compared. The experimental results illustrate that the developed SMA dampers are very effective to reduce structural response and have great potential for use as efficient energy dissipation devices.
