【摘要】 文章将SMA细丝作为桅杆结构的纤绳 ,它和PSD传感器、数据采集板、计算机、恒流源组成控制系统 ,以对桅杆的振动进行控制。桅杆结构在采用钢丝纤绳及SMA纤绳的自由振动的对比实验表明 ,处于超弹性状态的SMA纤绳可以有效地使结构振动得到衰减更多还原

【Abstract】 In this paper,SMA(Shape Memory Alloy)wires are used as a guyed mast model’s cable.The SMA cable,PSD senˉsors,a data acquisition board and a permanent currentelectric source compose a systemto control the mast’s vibration.The conˉtrastive tests of the mast structure supported by steel cables and by SMA cables showthat the SMA cable under super-elastic state can decrease the structure’s vibration effectively.更多还原
