Rocker type tuned mass damper damping device for vortex-induced vibration of box girder
The invention provides a rocker type tuned mass damper vibration reduction device for vortex-induced vibration of a box girder, and belongs to the field of vibration control, energy dissipation and vibration reduction. The vibration control device solves the problem of vibration control of up-down, left-right and torsion of a bridge, achieves the purposes of reducing vibration of the bridge and protecting the bridge from being damaged, and comprises a support, a rocker, a limiting sliding groove, a mass block and non-Newtonian fluid, the limiting sliding groove is formed in the bottom of the support, the mass block is arranged in the center of the bottom of the limiting sliding groove, and the support is connected with the mass block. The spaces, located on the two sides of the mass block, of the limiting sliding grooves are symmetrically filled with non-Newtonian fluid. Due to the design of the circular sliding groove, vibration of a bridge in the transverse direction, the vertical direction and the torsion direction under the action of wind vibration, earthquakes and vehicles can be reduced, and the vibration cannot be achieved by a traditional suspension type tuned mass damper device.
本发明提出了一种用于箱梁涡激振动的摇杆式调谐质量阻尼器减振装置，属于振动控制、消能减振领域。解决了桥梁的上下、左右和扭转的振动控制问题，达到减小桥梁的振动，保护桥梁不受损伤的目的，它包括支座、摇杆、限位滑槽、质量块和非牛顿流体，支座的底部安装有限位滑槽，限位滑槽的底部中心设置有质量块，支座与质量块连接，限位滑槽位于质量块两侧的空间对称填充有非牛顿流体。本发明由于采用了圆形滑槽的设计，可减小桥梁在风振、地震以及车辆作用下横向、竖向和扭转方向的振动，这是传统悬吊式调谐质量阻尼器装置所不能实现的。
