Damping device suitable for long-span bridge
The invention provides a damping device suitable for a large-span bridge, which comprises a mass block, a vertical linear spring, a first transverse linear spring, a second transverse linear spring, a damper, a first spring hanging plate and a second spring hanging plate, the first spring hanging plate and the second spring hanging plate are both connected to the bridge, and the vertical linear spring is arranged on the mass block and the bridge. The first transverse linear spring and the second transverse linear spring are arranged on the two opposite sides of the mass block, one end of the first transverse linear spring and one end of the second transverse linear spring are arranged on the mass block, and the other end of the first transverse linear spring is arranged on the first spring hanging plate. The other end of the second transverse linear spring is arranged on the second spring hanging plate, the two ends of the damper are connected to the mass block and the bridge respectively, the central axis of the vertical linear spring is parallel to the central axis of the damper, and the vertical linear spring can be selectively replaced so that the static stroke can be controlled. The damping device provided by the invention can realize static stroke controllability and wide frequency band.
本发明提供了一种适用于大跨桥梁的减振装置，包括质量块、竖向线性弹簧、第一横向线性弹簧、第二横向线性弹簧、阻尼器和均连接于桥梁的第一弹簧挂板和第二弹簧挂板，所述竖向线性弹簧设置于质量块和桥梁，所述第一横向线性弹簧和第二横向线性弹簧设置于所述质量块相对的两侧，所述第一横向线性弹簧和所述第二横向线性弹簧的一端均设置于所述质量块，第一横向线性弹簧的另一端设置于所述第一弹簧挂板，第二横向线性弹簧的另一端设置于所述第二弹簧挂板，所述阻尼器的两端分别连接于质量块和桥梁，竖向线性弹簧的中心轴线与阻尼器的中心轴线相平行，竖向线性弹簧可选择地更换以实现静力行程可控。该发明提供的减振装置可实现静力行程可控化和宽频带。
