Suspension bridge wind-resistant device
The invention discloses a suspension bridge wind-resistant device which comprises a rope and a damping device, the upper end of the rope is connected with the edge of a suspension bridge body in the length direction, the lower end of the rope is connected with the damping device, and the damping device is suspended in water by means of buoyancy of the damping device and tension provided by the rope; when wind-induced vibration of a beam body of the suspension bridge occurs, the beam body drives the damping device to move in water through the rope, the damping device bears resistance opposite to the movement direction when moving in water, the damping device needs to overcome the resistance of water to do work when moving up and down in a reciprocating mode, and therefore vibration energy of the beam body is dissipated, and the beam body is restored to the static state from the movement state.
本发明公开了一种悬索桥抗风装置，包括绳索和阻尼装置，所述绳索的上端与悬索桥梁体长度方向的边缘处相连接，所述绳索的下端与所述阻尼装置相连接，所述阻尼装置依靠自身浮力和所述绳索提供的拉力悬浮于水中；当悬索桥的梁体发生风致振动时，梁体通过绳索带动阻尼装置在水中运动，阻尼装置在水中运动时受到与运动方向相反的阻力，阻尼装置上下往复运动需克服水的阻力做功，从而耗散梁体振动的能量，使梁体由运动状态恢复到静止状态。
