Self-resetting damper with staged energy consumption
The invention belongs to the field of general structures for preventing vibration or vibration, and particularly relates to a self-resetting damper with staged energy consumption. The self-resetting damper capable of dissipating energy in stages comprises a deformation energy dissipation device and a friction energy dissipation device, energy dissipation is achieved through deformation and friction in sequence, the deformation energy dissipation device comprises a movable part and a fixed part, the friction energy dissipation device comprises at least two friction energy dissipation pieces and a clamping structure, the moving direction of the movable part is defined as the left-right direction, and the moving direction of the fixed part is defined as the left-right direction. In the left-right direction, a transmission device is hinged to each friction energy dissipation piece, and the transmission devices connected to every two adjacent friction energy dissipation pieces are hinged to the movable part and the fixed part so that every two adjacent friction energy dissipation pieces in one friction energy dissipation assembly can be movably matched in the left-right direction. The friction energy dissipation device is prevented from working in the first energy dissipation stage by means of static friction force existing between every two adjacent friction energy dissipation pieces, the mechanical mechanism is clear, the service life is long, the fortification capacity for large, medium and small earthquakes is achieved, adaptability is high, and stability is good.
本发明属于防振动或震动的一般构造领域，特别是涉及一种分阶段耗能的自复位阻尼器。本发明的分阶段耗能的自复位阻尼器包括变形耗能装置和摩擦耗能装置，依次通过变形和摩擦耗能，变形耗能装置包括活动部和固定部，摩擦耗能装置包括至少两个摩擦耗能件和夹紧结构，定义活动部的活动方向为左右方向，在左右方向上，各摩擦耗能件上均铰接有传动装置，且相邻两个摩擦耗能件上连接的传动装置与活动部和固定部分别铰接以使一组摩擦耗能组件中的相邻两个摩擦耗能件沿左右方向可移动配合。利用相邻两个摩擦耗能件间存在的静摩擦力，避免摩擦耗能装置在第一耗能阶段工作，力学机理清晰，使用寿命长、对大中小震均有设防能力，适应性强且稳定性好。
