Damper vibration reduction system for restraining vertical vibration of bridge girder
The invention belongs to the field of vibration control, and particularly relates to a damper vibration reduction system for restraining vertical vibration of a bridge girder. The damper vibration reduction system comprises a bridge pier tower and the bridge girder, and further comprises a torsional damper connected to the bridge pier tower, the torsional damper is connected with a rotating shaftfor driving the torsional damper to output damping force, a first connecting rod is connected to the rotating shaft, the rotating shaft and the first connecting rod can rotate together, a second connecting rod is hinged to the end, away from the rotating shaft, of the first connecting rod, the second connecting rod is hinged to the bridge girder, and the first connecting rod is longitudinally arranged along the bridge girder. The damper vibration reduction system for restraining the vertical vibration of the bridge girder can be used for controlling the vertical vortex vibration of a stiffening girder of a suspension bridge, and can adapt to longitudinal deformation and torsional motion of the stiffening girder.
本发明属于振动控制领域，具体涉及一种用于抑制桥梁主梁竖向振动的阻尼器减振系统，包括桥梁墩塔和桥梁主梁，还包括连接于桥梁墩塔上的扭转型阻尼器，扭转型阻尼器连接有用于带动所述扭转型阻尼器输出阻尼力的转动轴，所述转动轴上连接有连杆一，且所述转动轴能够与所述连杆一一起转动，所述连杆一远离所述转动轴的一端铰接有连杆二，所述连杆二与所述桥梁主梁相铰接，所述连杆一沿所述桥梁主梁纵向设置。本发明的一种用于抑制桥梁主梁竖向振动的阻尼器减振系统，能够用于悬索桥加劲梁竖向涡振控制，且能够适应加劲梁的纵向变形和扭转运动。
