Bridge flutter suppression device and using method thereof
The invention discloses a bridge flutter suppression device and a using method thereof. The suppression device comprises a stabilization plate, the stabilization plate is arranged in the middle of thewidth direction of the bridge, the stabilization plate is arranged in the bridge direction, the width direction of the stabilization plate is arranged in the vertical direction, the width of the through groove is matched with the thickness of the stabilization plate, anemometers are arranged on the two sides of the bridge and used for collecting incoming wind characteristic data, and the stabilization plate can ascend and descend. The device is adopted according to the characteristics of incoming wind, the stabilization plate is adjusted to ascend or descend; namely, the upward and downward extension ratio of the stabilization plate is adjusted, and flow fields near the upper and lower surfaces of the bridge are changed, so that the flutter stability of the bridge under the condition of different wind characteristics is improved, the applicability of the flutter suppression device in the aspect of improving the flutter stability of the bridge is expanded, the flutter suppression device is particularly suitable for 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.
本发明公开了一种桥梁颤振抑制装置及其使用方法，抑制装置包含稳定板，所述稳定板设于桥梁宽度方向的中部，所述稳定板沿顺桥向设置，所述稳定板的宽度方向沿竖向设置，所述通槽的宽度适配所述稳定板的厚度，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，所述稳定板能够升降。采用本装置根据来流风特性，来调节所述稳定板升高或降低，即调整所述稳定板向上和向下外伸的比例，以改变桥梁上下表面附近的流场，进而提高桥梁在不同风特性情况下的颤振稳定性，扩大了上述颤振抑制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。
