Self-resetting rotating friction damper with annular spring
The invention provides a self-resetting rotating friction damper with an annular spring. The self-resetting rotating friction damper comprises a pin shaft connecting assembly, a rotating assembly, a clamping plate and a pin shaft assembly. The rotating assembly is connected with the pin shaft connecting assembly in an inserted mode, the two clamping plates are symmetrically arranged on the two sides of the rotating assembly respectively, the pin shaft assembly penetrates through the pin shaft connecting assembly, the rotating assembly and the clamping plates at the same time, and the two ends of the pin shaft assembly abut against the outer sides of the two clamping plates through ring springs made of shape memory alloy materials respectively. A plurality of fan-shaped protruding blocks are arranged on the side, making contact with the clamping plate, of the rotating assembly, fan-shaped concave blocks are arranged on the side, making contact with the rotating assembly, of the clamping plate, and the fan-shaped protruding blocks are matched with the fan-shaped concave blocks. The energy-dissipation and self-resetting combined structure has the energy-dissipation capacity and the self-resetting capacity at the same time, damage and residual displacement borne by structural members can be effectively reduced when an earthquake occurs through combination of the energy-dissipation capacity and the self-resetting capacity, and the anti-seismic toughness of a building structure can be improved easily.
本发明提供一种带环形弹簧的自复位转动摩擦阻尼器，包括销轴连接组件、转动组件、夹板、销轴组件；转动组件与销轴连接组件插接，夹板设置有两个，两个夹板分别对称设置在转动组件两侧，销轴组件同时穿过销轴连接组件、转动组件、夹板，销轴组件两端分别通过采用形状记忆合金材料的环簧与两个夹板外侧抵接，转动组件与所述夹板接触的一侧设置有多个扇形凸块，夹板与所述转动组件接触的一侧设置有扇形凹块，扇形凸块与所述扇形凹块配合；该发明同时具有耗能能力和自复位能力，耗能和自复位能力的结合可有效减轻地震发生时结构构件所受的损伤和残余位移，有利于提高建筑结构的抗震韧性。
