Self-resetting lead friction-viscoelasticity composite damper and working method thereof
The invention relates to a self-resetting lead friction-viscoelasticity composite damper and a working method thereof. The damper comprises a vertical groove-shaped steel plate and an inner steel plate which is located in the groove-shaped steel plate and can slide up and down relative to the groove-shaped steel plate, and a spring assembly for pushing the inner steel plate to reset is connected between the upper end of the inner steel plate and the groove-shaped steel plate; a lead core penetrating through the bottom plate of the groove-shaped steel plate is embedded in the inner steel plate;a pair of friction steel plates driven by the inner steel plate to move up and down is arranged on the two sides of the middle of the inner steel plate. The outward ends of the friction steel platesare fixedly connected with friction material layers attached to the inner walls of side plates of the groove-shaped steel plate. A pair of shearing steel plates driven by the friction steel plate above to move up and down is arranged on the two sides of the lower end of the inner steel plate, and the shearing steel plates are connected with side plates of the groove-shaped steel plate through viscous-elastic material layers. The composite damper is simple in structure and convenient to produce and install, three energy consumption mechanisms of lead core energy consumption, friction energy consumption and viscoelastic consumption are combined, staged energy consumption is fully achieved, and the energy consumption capacity of the damper is improved.
本发明涉及一种自复位铅摩擦‑粘弹性复合阻尼器及其工作方法，包括竖立的槽形钢板以及位于槽形钢板内并能相对槽形钢板上下滑动的内钢板，内钢板上端和槽形钢板之间连接有推动内钢板复位的弹簧组件；所述内钢板上嵌装有穿过槽形钢板的底板的铅芯；所述内钢板中部两侧设置有一对由内钢板带动上下移动的摩擦钢板，摩擦钢板朝外一端固连有贴着槽形钢板的侧板内壁的摩擦材料层；内钢板下端两侧设置有一对由上方的摩擦钢板带动上下移动的剪切钢板，所述剪切钢板通过粘弹性材料层与槽形钢板的侧板连接在一起。该复合阻尼器构造简单、便于生产和安装，结合了铅芯耗能、摩擦耗能以及粘弹性耗三种耗能机制，充分实现了分阶段耗能，提高了阻尼器的耗能能力。
