Vibration reduction device, vibration reduction method and large-span bridge
The invention relates to the technical field of bridge vibration reduction, and discloses a vibration reduction device, a vibration reduction method and a large-span bridge. The large-span bridge comprises a plurality of piers and a main beam, wherein the plurality of piers are arranged at intervals, and cross beams are respectively arranged on the piers; the main beam is arranged on all of the cross beams; one vibration reduction device or two symmetrical vibration reduction devices are arranged on each pier; and each vibration reduction device of the main beam comprises a dowel bar, an amplifying rod and a damper, one end of the dowel bar is rotatably connected with the bottom, which is located outside the piers, of the main beam, the middle of the amplifying rod is rotatably arranged onthe cross beams or the piers, the amplifying rod comprises a connecting end and an amplifying end, the connecting end is rotatably connected with the other end of the dowel bar, one end of the damperis rotatably arranged on the cross beams or the piers, and the other end of the damper is rotatably connected with the amplifying end. According to the vibration reduction device, the problems of wind vibration including vortex vibration and vehicle vibration generated by the large-span bridge at specific wind speed in the prior art can be solved.
本发明涉及桥梁减振技术领域，公开了一种减振装置、减振方法及大跨度桥，该大跨度桥包括：多个间隔设置的桥墩，每个桥墩上均设有横梁；还包括主梁，其设于所有的横梁上；每个桥墩处设有一个减振装置或者两个对称设置的减振装置。每个主梁减振装置包括：传力杆，其一端与主梁位于桥墩外的底部转动连接；还包括中部可转动设置在横梁或者桥墩上的放大杆，其包括连接端和放大端，连接端与传力杆的另一端转动连接；还包括阻尼器，其一端可相对转动地设在横梁或者桥墩上，其另一端与放大端转动连接。该减振装置能够解决现有技术中大跨度桥梁在特定风速下产生包括涡振在内的风振及车振问题。
