Pneumatic wing plate damping device for bridge
The invention provides a pneumatic wing plate damping device for a bridge. The pneumatic wing plate damping device comprises a fixed supporting rod fixedly connected to a bridge box girder, a pneumatic wing plate rotatably connected to the bridge box girder, an elastic piece arranged between the fixed supporting rod and the pneumatic wing plate, and a first frequency modulation piece arranged on the fixed supporting rod. The two ends of the elastic piece are connected to the fixed supporting rod and the pneumatic wing plate correspondingly, when the amplitude of the pneumatic wing plate is smaller than a first set value, the first frequency modulation piece is far away from the pneumatic wing plate, and when the amplitude of the pneumatic wing plate is equal to or larger than the first set value, the second frequency modulation piece is far away from the pneumatic wing plate. And the other end of the first frequency modulation piece is automatically connected to the pneumatic wing plate. In the pneumatic wing plate damping device, the motion frequency of the pneumatic wing plate is adjustable, and the amplitude of the pneumatic wing plate can be limited to be further amplified so as to avoid structural damage.
本发明提供了一种用于桥梁的气动翼板减振装置，所述气动翼板减振装置包括固定连接于桥梁箱梁的固定支撑杆、可转动地连接于桥梁箱梁的气动翼板、设置于所述固定支撑杆和所述气动翼板之间的弹性件、设置于所述固定支撑杆的第一调频件，所述弹性件的两端分别连接于所述固定支撑杆和气动翼板，当所述气动翼板的振幅小于第一设定值时，所述第一调频件远离所述气动翼板，当所述气动翼板的振幅等于或大于第一设定值时，所述第一调频件的另一端自动连接于所述气动翼板。该气动翼板减振装置中，气动翼板运动频率可调，且能限制气动翼板振幅进一步放大以避免结构破坏。
