Active vibration suppression device for wind-induced vortex-induced vibration
The invention discloses an active vibration suppression device for wind-induced vortex-induced vibration. The active vibration suppression device comprises an air inlet hole, an air compressor, an air conveying pipeline, a ventilation inner pipe, a ventilation outer pipe and an exhaust device, and the ventilation inner pipe is arranged in the ventilation outer pipe through a first bearing; the air inlet is formed in the bridge body, the input end of the air inlet is located on the side face of the bridge body, and the output end of the air inlet is located on the upper surface or the lower surface of the bridge body and connected with the input end of the air compressor. The output end of the air compressor is connected with the air conveying pipeline, the other end of the air conveying pipeline is inserted into the bridge body and connected with the ventilation inner pipe through a second bearing, and the output end of the ventilation inner pipe penetrates out of the bridge body and is connected with the exhaust device. The exhaust device comprises an exhaust collecting pipe, an exhaust pipe and a drainage blade, the exhaust pipe is a bent pipe, and the drainage blade is arranged on the side wall of the exhaust pipe. According to the method, wind-induced vortex-induced vibration suppression can be efficiently and actively carried out on the bridge, and technical support is provided for guaranteeing bridge safety.
本发明公开了一种风致涡激振动主动抑振装置，包括进气孔、空压机、输风管道、通风内管、通风外管、排气装置，所述通风内管通过轴承一设置在所述通风外管内；所述进气孔设置在桥梁主体上，所述进气孔的输入端位于桥梁主体的侧面，输出端位于桥梁主体的上表面或下表面且与所述空压机的输入端相连；所述空压机的输出端与所述输风管道相连，所述输风管道的另一端插入桥梁主体通过轴承二与所述通风内管相连，所述通风内管的输出端穿出桥梁主体与所述排气装置相连；所述排气装置包括排气汇集管、排气管、引流叶片，所述排气管为弯管，所述引流叶片设置在排气管的侧壁。本发明能够高效、主动地对桥梁进行风致涡激振动抑振，为保证桥梁安全提供技术支持。
