Double-order self-recovery friction damper
The invention relates to the technical field of seismic resistance, in particular to a double-order self-recovery friction damper which comprises a first friction steel plate and a second friction steel plate which are in sliding friction fit with each other, and the first friction steel plate and the second friction steel plate are in cylindrical mutual insertion connection. An energy consumption assembly is arranged in a cavity formed between the first friction steel plate and the second friction steel plate in the sliding friction direction. Connecting end rods are arranged on the outer surfaces of the outer ends of the first friction steel plate and the second friction steel plate correspondingly, and the connecting end rods at the two ends are slidably sleeved with movable end plates correspondingly. Steel sleeves are arranged on the side faces, close to the outer ends, of the first friction steel plate and the second friction steel plate correspondingly, the ends of the steel sleeves abut against the movable end plates at the two ends correspondingly, SMA springs are arranged in the steel sleeves, and the ends of the SMA springs are anchored to the movable end plates at the two ends correspondingly. The defects that a traditional friction damper is poor in fatigue resistance, difficult to repair after an earthquake, too large in residual displacement and the like can be overcome.
本发明涉及抗震技术领域，具体为一种双阶自恢复摩擦阻尼器，包括相互滑动摩擦配合的第一摩擦钢板和第二摩擦钢板，第一摩擦钢板和第二摩擦钢板呈筒状相互插接，第一摩擦钢板和第二摩擦钢板之间形成的腔体内且沿滑动摩擦方向设置有耗能组件；第一摩擦钢板和第二摩擦钢板的外端外表面均设置有连接端杆，两端连接端杆上均滑动套设有移动端板；第一摩擦钢板和第二摩擦钢板上靠近外端的侧面位置均设置有钢套管，钢套管的端部分别与两端移动端板相抵，钢套管内设置有SMA弹簧，SMA弹簧的端部分别与两端移动端板锚固。可以解决传统摩擦阻尼器存在的耐疲劳性较差、震后修复困难、残余位移过大等缺点。
