Damping device for bridge floor and bridge pier of suspension bridge
The invention discloses a damping device for a bridge floor and a bridge pier of a suspension bridge, which belongs to the technical field of suspension bridges and comprises a bridge floor, a bridge pier, a fixing block, a first torsion spring, a buffer strip and a pushing block. When vibration is transmitted to a bridge floor, a fixing block compresses a first spring damper to move, and when the vibration is increased and the moving degree of the fixing block is increased, sliding friction is generated between a buffer strip and the side wall of a fixing groove, so that the effect of energy consumption again is achieved; when first-time energy consumption occurs, the buffer strips can abut against the fixing grooves in time, and second-stage energy consumption of friction force is achieved; before vibration is transmitted to the bridge pier, the first spring dampers and the buffer strips are used for consuming energy generated when the bridge deck bears vibration loads, the vibration of the bridge deck is prevented from being transmitted to the bridge pier in time, and periodic displacement loading positions are prevented from being generated on the bridge pier; therefore, fatigue damage of materials of the bridge pier is avoided, and the strength and long-term stability of the bridge deck are kept.
本发明公开了一种用于悬索桥桥面和桥墩的减震装置，属于悬索桥技术领域，包括桥面、桥墩、固定块、第一扭簧、缓冲条以及推动块；当发生振动传递给桥面时，固定块压缩第一弹簧阻尼器移动，当振动增大而使固定块的移动程度增大时，缓冲条与固定槽的侧壁产生滑动摩擦的情形，从而达到再次耗能的效果；在出现首次耗能的同时，缓冲条能够及时抵紧固定槽并实现摩擦力的二级耗能；能够在振动传递到桥墩之前，利用第一弹簧阻尼器和缓冲条消耗桥面受到振动载荷而产生的能量，及时的阻碍桥面的振动传递给桥墩，避免桥墩上产生周期性的位移载位；从而避免桥墩的材料的产生疲劳破坏，保持桥面的强度和长期的稳定性。
