Longitudinal electromagnetic-viscous composite damping system and vibration/seismic reduction method for long-span bridge
The long-span bridge longitudinal electromagnetic-viscous composite damping system comprises an electromagnetic damper and a viscous damper which are arranged in parallel, the vibration/vibration reduction direction of the electromagnetic damper is in the longitudinal direction of a bridge, one end of the viscous damper is connected with a first bridge structure, and the other end of the viscous damper is connected with a second bridge structure through a fusing-locking device. The fusing-locking device comprises a mounting seat, a lower tooth block plate and an upper tooth block plate, the mounting seat is fixedly mounted on the first bridge structure, a sliding clamping groove extending in the longitudinal direction of a bridge is formed in the mounting seat, the lower tooth block plate is mounted in the sliding clamping groove, the other end of the viscous damper is connected with the lower tooth block plate, a positioning tooth block is arranged on the upper tooth block plate, and the positioning tooth block is connected with the upper tooth block plate. A positioning tooth groove is formed in the lower tooth block plate, and a lifting mechanism for driving the upper tooth block plate to move up and down so as to enable the positioning tooth block to be inserted into or withdrawn from the positioning tooth groove is connected between the upper tooth block plate and the mounting seat. According to the system, through switching of working states of different dampers, vibration-vibration double-control integration can be achieved, and the system has the advantage of being high in load adaptability.
本发明公开了一种大跨度桥梁纵向电磁‑黏滞复合阻尼系统，包括并联布置且减振/震方向沿桥梁纵向的电磁阻尼器和黏滞阻尼器，黏滞阻尼器一端与第一桥梁结构连接，另一端通过熔断‑锁定装置与第二桥梁结构连接，熔断‑锁定装置包括安装座、下齿块板和上齿块板，安装座固定安装在第一桥梁结构上，安装座上设有沿桥梁纵向延伸的滑动卡槽，下齿块板安装在滑动卡槽中，黏滞阻尼器的另一端与下齿块板连接，上齿块板上设有定位齿块，下齿块板上设有定位齿槽，上齿块板与安装座之间连接有带动上齿块板上下移动以将定位齿块插入或退出定位齿槽的升降机构。该系统通过不同阻尼器工作状态的切换，可实现振震双控集成化，具有荷载适应性强的优点。
