Multi-dimensional vibration/shock absorption composite damping system and method for long-span bridge
The invention discloses a large-span bridge multi-dimensional vibration/seismic reduction composite damping system which comprises a mild steel damper and an electromagnetic damper which are arranged in parallel, the vibration/seismic reduction direction of the electromagnetic damper is arranged in the longitudinal direction of a bridge, one end of the electromagnetic damper is used for being hinged to a bridge tower, and the other end of the electromagnetic damper is used for being hinged to the top of an extending arm fixed to the lower end of a main beam. The mild steel damper comprises an anchor plate, a plurality of damping tenons and a force transmission seat, the anchor plate is used for being anchored to a bridge tower, the bottom ends of the damping tenons are fixedly installed on the anchor plate, the top end of each damping tenon is provided with a spherical tenon, the extending direction of each damping tenon is parallel to the longitudinal direction of a bridge, and the force transmission seat is used for being connected with the root of the extending arm. A sliding cavity extending in the longitudinal direction of the bridge is formed in the force transmission base, a spherical hinge support is installed in the sliding cavity in a sliding mode, and the spherical tenon is installed in a corresponding spherical hinge cavity in the spherical hinge support in a matched mode. The composite damping system can realize multi-dimensional vibration control of vertical rotation angle, vertical displacement, longitudinal displacement and transverse displacement of the main beam.
本发明公开了一种大跨度桥梁多维减振/震复合阻尼系统，包括并联设置的软钢阻尼器和电磁阻尼器，电磁阻尼器的减振/震方向沿桥梁纵向设置，电磁阻尼器的一端用于与桥塔铰接，另一端用于与固定在主梁下端的伸臂顶部铰接，软钢阻尼器包括锚板、多根减震榫和传力座，锚板用于与桥塔锚固，多根减震榫的底端固定安装在锚板上，每个减震榫的顶端设有球形榫头，减震榫的延伸方向与桥梁纵向平行，传力座用于与伸臂的根部连接，传力座上形成有沿桥梁纵向延伸的滑动腔，滑动腔中滑动安装有球铰支座，球形榫头匹配安装在球铰支座上对应的球铰腔内。该复合阻尼系统可实现主梁竖向转角、竖向位移、纵向位移和横向位移的多维振动控制。
