摘要
利用形状记忆合金的优良力学性能,设计出了一种性能良好的SMA-粘滞阻尼器,利用分段线性化模型推导出阻尼器的力学性能,并进行了仿真计算.计算结果表明:该阻尼器有良好的耗能能力,在大跨度桥梁低频振动控制方面有较好的应用前景.
In this paper, a new type of shape memory alloy（SMA）-fluid viscous damper is proposed by utilizing the super-elastic property of SMA. A theoretical model has been developed from sectionally linearized super-elastic restoring force model of SMA, and a simulation of the damper has been done. Through studying , it is ob- tained that this damper is good in energy dissipation and has a great potential for using in controlling low frequency of long-span bridges.
