Structure vortex-induced vibration suppression device
The invention relates to the technical field of vortex-induced vibration, and particularly relates to a structure vortex-induced vibration suppression device. A structure is suspended and arranged in a straddling mode in the longitudinal direction and provided with a first side edge and a second side edge which are opposite in the transverse direction; the structure vortex-induced vibration suppression device comprises a plurality of flow guide plates suspended on the structure; the plurality of flow guide plates are sequentially arranged at the first side edge and the second side edge in the longitudinal direction; and the upper ends of the flow guide plates are hinged to the structure in the mode of being capable of rotating in the longitudinal direction. When crosswind blows through the structure, the flow guide plates rotationally suspended at the first side edge and the second side edge of the structure are blown by the crosswind to swing, the flow guide plates on the leeward side float along with the crosswind, and therefore the pneumatic shape of the structure is changed, the original vortex generation and falling pneumatic performance of the structure is damaged, an original vortex generation mechanism of the structure is disturbed, vortex falling of the leeward side of the structure can be suppressed, vortex-induced vibration is suppressed, harm caused by wind-induced vortex-induced vibration is reduced, and the structure safety of the structure is guaranteed.
本发明涉及涡激振动技术领域，尤其涉及一种结构物涡激振动抑制装置，结构物沿纵向悬空跨设，结构物具有沿横向相对的第一侧缘和第二侧缘，结构物涡激振动抑制装置包括悬挂在结构物上的多个导流板，多个导流板在第一侧缘处和第二侧缘处沿纵向依次排布，导流板的上端可绕纵向转动地铰接在结构物上。有横风吹过结构物时，可转动地悬挂在结构物第一侧缘和第二侧缘处的导流板被横风吹动摆起，背风侧的导流板则随横风飘起，由此改变了结构物的气动形状，破坏了结构物原有涡生成与脱落的气动性能，扰乱了结构物的原有涡生成机制，能够抑制结构物背风侧的涡脱落，从而抑制涡激振动的发生，降低风致涡激振动带来的危害，保障结构物的结构安全。
