Overhaul car rail wind-induced vibration suppression device for straight web steel box girder
The invention discloses a maintenance car track wind-induced vibration suppression device for a straight web steel box girder, and belongs to the technical field of bridge engineering, the maintenance car track wind-induced vibration suppression device comprises a steel box girder and a detection car track arranged at the bottom of the steel box girder, turbulent flow vibration suppression devices are arranged on the two sides of the detection car track, and each turbulent flow vibration suppression device comprises a vertical back plate and a plurality of wind suppression plates; the vertical back plates are fixedly connected with the steel box girder, the wind suppression plates are evenly arranged at intervals in the length direction of the vertical back plates, a certain included angle is formed between the plane where the wind suppression plates are located and the horizontal plane, the length direction of the wind suppression plates is in the longitudinal direction of the steel box girder, and the rotating rods are connected with rotating damping devices at the same time. The wind suppression plate drives the rotating rod to rotate under the action of airflow, the rotating rod acts on the rotating damping device, and energy is dissipated through the rotating damping device. The device can be used for crushing airflow vortexes at a track of a maintenance car, and the vortex vibration amplitude of the box girder is reduced, so that wind-induced vibration on the steel box girder is inhibited.
本发明公开了一种用于直腹板钢箱梁的检修车轨道风致振动抑振装置，属于桥梁工程技术领域，包括钢箱梁以及设置在钢箱梁底部的检测车轨道，检测车轨道的两侧均设置有紊流抑振装置，紊流抑振装置包括竖直背板以及若干抑风板，竖直背板与钢箱梁固定连接，抑风板沿竖直背板的长度方向均匀间隔布置，抑风板所在平面与水平面呈一定夹角，抑风板的长度方向沿着钢箱梁的纵向，转动杆同时连接有旋转阻尼装置，抑风板用于对气流漩涡进行破碎，抑风板在气流的作用下带动转动杆旋转，转动杆作用于旋转阻尼装置，通过旋转阻尼装置耗散能量。本发明装置可以用于对检修车轨道处的气流漩涡进行破碎，减少箱梁涡振振幅，从而抑制钢箱梁上风致振动的产生。
