Displacement response amplification type friction energy dissipation damper based on gear transmission
The invention provides a displacement response amplification type friction energy dissipation damper based on gear transmission, is mainly applied to energy dissipation and seismic mitigation of building structures, and belongs to the technical field of structural vibration control. The device is composed of a damper shell, a gear response amplifying device, an upper rack rod, a lower rack rod, afriction plate, a rack sliding block, a guide hole, a gear device fixing hole and a square iron plate. The gear response amplifying device is fixed through a gear device fixing hole and driven by theupper rack rod and the lower rack rod to rotate, so that the rack sliding block and the square iron plate are driven to move relative to the friction plate, and energy dissipation and shock absorptionare achieved through the friction energy dissipation characteristic of the damper. Meanwhile, the device amplifies the relative displacement of the building through the gear response amplifying device, so that the displacement response received by the energy dissipation mechanism is amplified, and the energy dissipation capacity of the damper is improved. The novel shock absorption and energy dissipation damper has a good application prospect in earthquake fortification.
