Device for restraining wind-induced vortex vibration of suspension bridge

The utility model discloses a device for restraining wind-induced vortex vibration of a suspension bridge. The device comprises a main beam, a main tower, a cantilever supporting platform, a damping vibration attenuation device and a beam end connecting piece. The cantilever supporting platform is arranged at the side part of the main tower and is anchored with the main tower; the damping vibration attenuation device is arranged on the supporting platform, the upper end of the damping vibration attenuation device is connected with the main beam through a beam end connecting piece, and the lower end of the damping vibration attenuation device is connected with the cantilever supporting platform; according to the method, the additional damping ratio of related modes of the main beam structure can be increased, so that the vertical vortex-induced amplitude of the main beam is reduced, and multi-order and high-order mode wind-induced vortex vibration of the main beam structure is inhibited. 本实用新型公开了一种抑制悬索桥风致涡振的装置
