Vortex-vibration-resistant damper and suspension cable highway bridge deck
The invention provides a vortex-vibration-resistant damper and a suspension cable highway bridge deck. The vortex-vibration-resistant damper comprises a left framework structure end and a right framework structure end, the left framework structure end and the right framework structure end are connected through a bridge floor gap guide rail in the middle, a load balance spring is arranged on one side of the bridge floor gap guide rail, and a piston damper is arranged on the other side of the bridge floor gap guide rail. According to the anti-vortex-vibration damper and the bridge floor of the suspension cable highway bridge, the purposes of actively preventing vortex vibration of the suspension bridge or reducing the vortex vibration amplitude when the vortex vibration occurs and accelerating and attenuating the vortex vibration amplitude are achieved.
本发明提供了一种抗涡振阻尼器及悬索公路桥桥面。该抗涡振阻尼器包括：左骨架结构端及右骨架结构端，所述左骨架结构端与所述右骨架结构端通过中间的桥面缝隙导轨连接，在桥面缝隙导轨的一侧，设置有负载平衡弹簧，在桥面缝隙导轨的另一侧，设置有活塞阻尼器。本发明提供的抗涡振阻尼器及悬索公路桥桥面达到主动防止悬索桥涡振发生或在涡振发生时减轻涡振振幅并是涡振振幅加速衰减的目的。
