Self-resetting variable-friction composite collision pendulum damper
The invention discloses a self-resetting variable-friction composite collision pendulum damper which comprises a metal ball, a suspension device, a variable-friction device and a support. The metal ball is suspended in the support through a suspension device, and variable friction devices are oppositely arranged on the two sides of the metal ball respectively and installed in the support through a connecting structure. The variable friction device comprises a limiting plate vertically arranged on one side of the metal ball and an upper friction plate and a lower friction plate which are arranged at the upper end and the lower end of the limiting plate, and the upper friction plate and the lower friction plate which are arranged in the horizontal direction are connected with the limiting plate through elastic structures; high-damping rubber materials are arranged on the limiting plate, the upper friction plate and the lower friction plate; the damper has the self-resetting function and the variable friction function at the same time through the arranged variable friction device, on one hand, it is effectively guaranteed that post-earthquake residual deformation of the structure is controlled, on the other hand, the energy dissipation capacity of the damper can be improved through the collision energy dissipation process and the variable friction energy dissipation process, and effective damping of the building structure is achieved.
本发明公开了一种自复位变摩擦复合碰撞摆阻尼器，包括金属球、悬挂装置、变摩擦装置以及支架；金属球通过悬挂装置悬吊于支架内部，金属球两侧分别相对设置有变摩擦装置，变摩擦装置通过连接结构安装于支架内；变摩擦装置包括竖向设置在金属球一侧的限位板以及设置于限位板上下两端的上摩擦板和下摩擦板，沿水平方向设置的上摩擦板和下摩擦板通过弹性结构与限位板连接；限位板、上摩擦板以及下摩擦板上均设有高阻尼橡胶材料；设置的变摩擦装置使得本阻尼器同时具有自复位与变摩擦功能，一方面有效保证控制结构的震后残余变形，另一方面具有的碰撞与变摩擦两种耗能过程能够提高阻尼器的耗能能力，实现建筑结构的有效减震。
