Vortex-induced vibration suppression device for large-span bridge
The invention relates to a large-span bridge vortex-induced vibration suppression device, and belongs to the technical field of bridge safety, the large-span bridge vortex-induced vibration suppression device comprises a flow guide assembly and a fixing assembly, the flow guide assembly comprises an arc-shaped flow guide plate, one end of the arc-shaped flow guide plate is connected with the fixing assembly, an acute angle is formed between the arc-shaped flow guide plate and the fixing assembly, and a spoiler is arranged at the other end of the arc-shaped flow guide plate; torsion springs are arranged at the two ends of the spoiler respectively, one ends of the torsion springs are connected with the spoiler, the other ends of the torsion springs are connected with the arc-shaped flow guide plate, the spoiler comprises a first arc-shaped part and a second arc-shaped part, and the first arc-shaped part can abut against and be attached to the flow guide plate. The arc-shaped part II is fixedly connected with the arc-shaped part I; and the radian bending direction of the arc-shaped part II is opposite to that of the arc-shaped flow guide plate. The method has the effect of reducing the possibility of vortex-induced vibration of the bridge.
本申请涉及一种大跨度桥梁涡激振动抑制装置，属于桥梁安全的技术领域，包括导流组件以及固定组件，导流组件包括弧形导流板，弧形导流板一端与固定组件连接且弧形导流板与固定组件之间形成有锐角，弧形导流板另一端设有扰流板，扰流板的两端分别设有扭簧，扭簧一端与扰流板连接，扭簧的另一端与弧形导流板连接，扰流板包括弧形部一与弧形部二，弧形部一可与导流板抵靠并贴合，弧形部二与弧形部一固定连接且弧形部二的弧度弯曲方向与弧形导流板的弧度弯曲方向相反。本申请具有降低桥梁发生涡激振动可能性的效果。
