Self-resetting graded friction incremental energy consumption damper
The invention relates to a self-resetting graded friction incremental energy dissipation damper which comprises a friction energy dissipation system, resetting systems and a lever system, the friction energy dissipation system is arranged in the lever system, the resetting systems are arranged at the two ends of the friction energy dissipation system, the resetting system at one end is fixedly connected with the lever system, and the resetting system at the other end is fixedly connected with the lever system. The steel rod penetrates through the friction energy dissipation system, and the two ends of the steel rod are movably connected with the lever system. The device can more flexibly cope with large and small vibration effects, the friction energy dissipation system and the reset system work at the same time under small displacement, and the self-reset function and friction energy dissipation under small displacement are achieved; the friction energy dissipation system, the lever system and the reset system work at the same time under large displacement, the lever system conducts displacement amplification type friction energy dissipation, double friction energy dissipation of the damper under large displacement is achieved, in the automatic reset process, the lever system does not consume energy, and the friction energy dissipation system can promote complete reset of the building while reducing the influence of external vibration on the building.
