Self-resetting friction metal yield damper with secondary amplification function
The self-resetting friction metal yield damper with the secondary amplification function comprises an inner friction plate and an outer friction plate which are located in the center in a constraint box, a resetting combined disc spring is arranged between the outer friction plate and the constraint box, and energy dissipation steel bars are arranged in the circumferential direction of the inner friction plate; the left side and the right side of the inner friction plate are respectively provided with an amplification lever structure in a central symmetry mode, the amplification lever structures are connected with the loading shaft rod and the inner friction plate, the amplification lever structures amplify the displacement of the loading shaft rod for the first time, then the inner friction plate amplifies the displacement for the second time, the energy dissipation steel bar dissipates energy, and the inner friction plate and the outer friction plate rub to dissipate energy. The inner friction plate and the outer friction plate axially displace after relatively rotating, the inner friction plate and the outer friction plate are reset after unloading, and the reset combined disc spring enables the energy dissipation steel bar to reset. The metal damper has a metal yield and friction dual energy dissipation mechanism, can adapt to energy dissipation under a low displacement level, and makes up for the problem that a traditional metal damper is difficult to structurally consume energy under the low displacement level.
本发明提供一种具有二次放大功能的自复位摩擦金属屈服阻尼器，包括位于约束盒内中心的内摩擦板和外摩擦板，外摩擦板与约束盒之间具有复位组合碟簧，内摩擦板的周向具有耗能钢棒；内摩擦板的左右两侧分别中心对称设置有放大杠杆结构，放大杠杆结构连接加载轴杆和内摩擦板，放大杠杆结构对加载轴杆的位移进行第一次放大，之后内摩擦板进行二次放大，耗能钢棒进行耗能，且内摩擦板与外摩擦板摩擦耗能，内摩擦板与外摩擦板相对转动后发生轴向位移，卸载后内摩擦板和外摩擦板复位，且复位组合碟簧使耗能钢棒复位。本发明具有金属屈服和摩擦双重耗能机制，能够适应低位移水平下耗能，弥补传统金属阻尼器的难以在低位移水平下结构的耗能需求。
