Vibration reduction wind barrier with variable posture
The invention relates to a variable-posture vibration reduction wind barrier which comprises a plurality of stand columns arranged on a bridge floor at intervals along the edge of the bridge floor, a vibration reduction wind shielding assembly is arranged between any two adjacent stand columns, and each vibration reduction wind shielding assembly comprises a plurality of wind shielding blades arranged from top to bottom. The two ends of each wind blocking blade are connected with the adjacent stand columns in a swinging mode. The wind blocking blades of the vibration reduction wind barrier dynamically change the pitching posture and the vibration amplitude at different wind speeds, the vehicle driving safety and comfort under strong wind are improved, and the wind-induced effect of a large-span cable bearing bridge is reduced. Compared with the prior art, the wind barrier is good in vibration reduction and suppression effect on a bridge structure under the wind load effect.
本发明涉及一种可变姿态的减振风屏障，该减振风屏障包括沿桥面边缘间隔设置在桥面的若干个立柱，任意两个相邻立柱之间设有一组减振挡风组件，所述减振挡风组件包括若干个由上至下布置的挡风叶片，每个挡风叶片的两端分别与相邻的立柱摆动连接。本发明减振风屏障的挡风叶片在不同风速下动态改变俯仰姿态和振动幅度，既提高强风下车辆行车安全性和舒适性，又减小大跨度缆索承重桥梁风致效应。与现有技术相比，本发明风屏障对于风荷载作用的桥梁结构的减振抑振效果佳。
