Device for restraining flutter of bridge and using method thereof
The invention discloses a device for restraining flutter of a bridge and a using method thereof. The device comprises two stabilizing plates, and the stabilizing plates are slidably connected to chutes through sliding blocks. The chutes are formed in the transverse direction of the bridge. The stabilizing plates are hinged to the sliding blocks, the stabilizing plates are arranged in the bridge direction, the two stabilizing plates can rotate to the vertical direction on the two side faces of the bridge respectively, anemometers are arranged on the two sides of the bridge and used for collecting incoming wind characteristic data, and the ventilation rate of the stabilizing plates is larger than 0. With the adoption of the device, the flutter performance of the bridge under different incoming flow conditions can be improved, the flutter stability of the bridge under different wind characteristics is improved, the applicability of the device in the aspect of improving the flutter stability of the bridge is expanded, the device is particularly suitable for large-span bridge engineering of mountainous terrains with complex wind environments, and the safety and stability of the bridge in the actual operation process are effectively guaranteed.
本发明公开了一种抑制桥梁颤振的装置及其使用方法，装置包含两个稳定板，所述稳定板通过滑块滑动连接于滑槽，所述滑槽沿桥梁的横桥向设置，所述稳定板铰接于所述滑块，所述稳定板沿顺桥向设置，两个所述稳定板能够分别在所述桥梁的两侧面转动至竖向方向，所述桥梁的两侧设有风速仪，所述风速仪用于采集来流风特性数据，所述稳定板的透风率大于0。采用本装置能够实现对桥梁在不同来流条件下颤振性能的改善，提高桥梁在不同风特性情况下的颤振稳定性，扩大了本装置在提高桥梁颤振稳定性方面的适用性，特别适用于风环境复杂的山区地形的大跨度桥梁工程，有效保证桥梁在实际运营过程中的安全性和稳定性。
