Self-limiting reset composite friction pendulum support with variable friction coefficient
The invention discloses a self-limiting reset composite friction pendulum support with a variable friction coefficient. The self-limiting reset composite friction pendulum support comprises a first energy dissipation pendulum seat, a central energy dissipation block, a second energy dissipation pendulum seat, a high-damping rubber-spring ring, a viscous damper and a shape memory alloy spring. The device has four energy dissipation mechanisms, the central energy dissipation sliding block is located between the first energy dissipation swing seat and the second energy dissipation swing seat, and the friction coefficients of friction plates between the central energy dissipation sliding block and the first energy dissipation swing seat and between the central energy dissipation sliding block and the second energy dissipation swing seat are sequentially increased from inside to outside; the friction coefficient of the friction plate between the stainless steel sliding plate and the stainless steel supporting plate is sequentially increased from inside to outside; a high-damping rubber-spring ring is arranged on the inner side of the displacement restraint ring; the viscous damper is installed between the first energy dissipation swing seat and the second energy dissipation swing seat in an X-shaped hinged mode. The shape memory alloy springs are installed among the four corners of the first energy dissipation swing seat and the four corners of the second energy dissipation swing seat in a hinged mode. The seismic isolation device can accurately recognize an earthquake, has excellent damping and rigidity self-adaptive adjusting capacity, is high in seismic reduction and energy dissipation capacity, has excellent self-limiting and resetting functions, and belongs to the technical field of seismic isolation.
本发明公开了一种自限位复位摩擦系数可变的复合摩擦摆支座，包括第一耗能摆座，中心耗能块，第二耗能摆座，高阻尼橡胶‑弹簧环，粘滞阻尼器，形状记忆合金弹簧；本发明具有四个耗能机制，中心耗能滑块位于第一耗能摆座、第二耗能摆座之间，中心耗能滑块与第一耗能摆座、第二耗能摆座之间摩擦板的摩擦系数由内向外依次增大；不锈钢滑板与不锈钢托板之间摩擦板的摩擦系数由内向外依次增大；位移约束环的内侧设有高阻尼橡胶‑弹簧环；粘滞阻尼器以“X”型铰接安装在第一耗能摆座、第二耗能摆座之间；形状记忆合金弹簧铰接安装在第一耗能摆座和第二耗能摆座的四角之间。本发明能够精准识别地震，具有优秀的阻尼、刚度自适应调节能力，减震耗能能力强，且具有优秀的自限位、复位功能，属于隔震技术领域。
