Vibration suppression device for steel-concrete combined box girder bridge under axle coupling effect
The invention discloses a vibration suppression device for a steel-concrete combined box girder bridge under the axle coupling effect, and belongs to the technical field of bridge engineering.The vibration suppression device comprises wind breaking plate assemblies installed on the two sides of a steel box girder, each wind breaking plate assembly comprises a plurality of wind breaking plates spliced side by side, and two side plates are installed on the sides, away from the steel box girder, of the wind breaking plates; the sides, away from each other, of the two side plates are obliquely arranged towards the side close to the steel box girder so that a tip can be formed at the joint of the two side plates, a plurality of wind breaking pieces capable of rotating are detachably mounted on the sides, away from the steel box girder, of the side plates through mounting plates, and the wind breaking pieces are arranged along the side plates. And a plurality of fan blades are circumferentially mounted on the wind breaking piece by taking the axis of the wind breaking piece as the center. Wind diffuses along the side plates on the two sides of the tip, so that vortexes on bluff body sections on the two sides of a bridge are scattered, and the influence of falling of the vortexes at the tail of the sections of the bridge on the sections can be reduced; and the wind breaking pieces are arranged along the side plates, so that wind blown to the side plates in any direction can be scattered.
本发明公开了一种用于车桥耦合作用下钢混组合箱梁桥的抑振装置，属于桥梁工程技术领域，包括：安装在钢箱梁两侧的破风板组件，所述破风板组件包括多个并排拼接成的破风板，所述破风板上远离钢箱梁侧安装有两个侧板，两个侧板相远离侧往靠近钢箱梁侧倾斜设置以使两个侧板连接处形成尖端，所述侧板远离钢箱梁侧通过安装板可拆卸安装有多个能够自转的破风件，多个所述破风件沿侧板排列设置，所述破风件上以破风件轴线为中心周向安装有多个扇叶。本发明使风沿尖端两侧的侧板扩散，从而打散桥梁两侧钝体断面上的漩涡，并且可以减小桥梁断面尾部的漩涡脱落对断面的影响；且破风件沿侧板排列布置，使得经任意方向吹向侧板的风都能被打散。
