Bridge vortex-induced vibration control device and bridge
The invention belongs to the technical field of bridges, and particularly provides a bridge vortex-induced vibration control device and a bridge. The bridge vortex-induced vibration control device comprises a guide rail, a moving platform, a web, a first driving mechanism, a bottom plate and a second driving mechanism, the moving platform can move in the length direction of the guide rail, the first driving mechanism can adjust the inclination angle of the web, and the second driving mechanism can adjust the inclination angle of the bottom plate. The position of the movable platform and the inclination angles of the web and the bottom plate can be adjusted according to the change condition of the wind environment, so that the flow path of wind is effectively optimized, and the direct impact of wind load on a bridge is reduced. The bridge vortex-induced vibration control device overcomes the limitation caused by the fact that a traditional passive control measure depends on a fixed structure design, the flexibility and adaptability of the control effect of the bridge vortex-induced vibration control device are improved, and it is ensured that the bridge vortex-induced vibration control device can play the best effect under the conditions of different wind speeds and wind directions.
本发明属于桥梁技术领域，具体提供了一种桥梁涡激振动控制装置及桥梁。桥梁涡激振动控制装置包括导轨、移动平台、腹板、第一驱动机构、底板和第二驱动机构，移动平台能够沿导轨的长度方向移动，第一驱动机构能够对腹板的倾斜角度进行调节，第二驱动机构能够对底板的倾斜角度进行调节。本发明能够根据风环境的变化情况调节移动平台的位置，以及腹板和底板的倾斜角度，从而有效优化风的流动路径，降低风荷载对桥梁的直接冲击。本发明克服了传统的被动控制措施依赖于固定结构设计所造成的局限性，提高了自身的控制效果的灵活性和适应性，确保桥梁涡激振动控制装置在不同风速和风向条件下都能发挥最佳效果。
