Suspender structure with wind-resistant stability
The invention relates to the field of bridge engineering, and discloses a suspender structure with wind-resistant stability, the suspender structure comprises a center rod, multiple sections of vibration reduction cylinders and multiple groups of damping pieces, the multiple sections of vibration reduction cylinders sleeve the outer side of the center rod, and the multiple sections of vibration reduction cylinders are arranged at intervals in the length direction of the center rod; the multiple sets of damping pieces and the multiple sections of vibration reduction cylinders are arranged in a one-to-one correspondence mode, the damping pieces are fixedly connected between the corresponding vibration reduction cylinders and the center rod so as to support the vibration reduction cylinders, and a flow guide plate is arranged on the outer side of each vibration reduction cylinder. The wind power on the peripheral side of the vibration reduction barrel can be guided through the flow guide plates arranged on the outer side of the vibration reduction barrel, the direction of a wind field is changed, a uniform flow field is broken, and the possibility that the suspender generates wind-induced vibration is reduced under the combined action of the damping pieces and the flow guide plates.
本申请涉及桥梁工程的领域，公开了一种具有抗风稳定性的吊杆结构，其包括中心杆、多节减振筒和多组阻尼件，多节所述减振筒均套设在所述中心杆的外侧，多节所述减振筒沿所述中心杆的长度方向间隔设置，多组所述阻尼件与多节所述减振筒一一对应设置，所述阻尼件固定连接在其对应的所述减振筒与所述中心杆之间以对所述减振筒进行支撑，每个所述减振筒的外侧均设置有导流板。本申请能够利用减振筒外侧设置的导流板对减振筒周侧的风力进行导流，改变风场的方向，破碎均匀流场，在阻尼件和导流板的共同作用下降低吊杆产生风致振动的可能。
