Wall type self-resetting sliding friction damper
According to the wall type self-resetting sliding friction damper, a T-shaped inner plate and L-shaped outer plates on the two sides are connected and fixed through bolts, slope surfaces capable of being attached are machined on the T-shaped inner plate and the L-shaped outer plates, and when the T-shaped inner plate and the L-shaped outer plates relatively move in the horizontal direction, the L-shaped outer plates on the two sides move outwards, and disc springs are pressed to deform. Pressure generated by deformation of the disc springs causes normal force between the slope surfaces, then friction force is generated, meanwhile, the pressure generated by deformation of the disc springs changes along with changes of deformation, and a variable friction mechanism is achieved. The energy dissipation capacity of the damper is achieved through friction energy dissipation between the first slope surface and the second slope surface. And the elasticity of the disc spring realizes the self-resetting performance of the damper. Compared with a traditional wall type damper, the damper has the outstanding self-resetting capacity, and residual deformation of the structure can be effectively reduced.
本发明公开了一种墙式自复位滑动摩擦阻尼器，T形内板和两侧L形外板通过螺栓连接固定，T形内板和L外板上均加工有可贴合的坡面，当T形内板与L形外板发生水平方向相对移动时，两侧L形外板向外移动，碟簧受压变形。碟簧变形产生的压力引起坡面之间的法向力，进而产生摩擦力，同时碟簧变形产生的压力大小随变形量的变化而变化，实现了变摩擦机制。该阻尼器的耗能能力由第一坡面与第二坡面之间的摩擦耗能实现。碟簧的弹性实现阻尼器的自复位性能。相较于传统墙式阻尼器，该阻尼器具有杰出的自复位能力，可有效减小结构残余变形。
