The invention relates to the technical field of structural engineering and vibration control, in particular to a tower end installed inhaul cable vibration reduction system which comprises a damper, a supporting rod and a connecting rod. The top end of the connecting rod is connected with the middle of the inhaul cable, the other end of the connecting rod is movably connected with the top end of the damper, and the bottom end of the damper is fixed to the tower through a bearing. The middle of the connecting rod is connected with the bottom end of the supporting rod; the top end of the supporting rod is fixed on the tower; the connecting position of the supporting rod and the tower is higher than the connecting position of the damper and the tower; when the inhaul cable vibrates in the vertical direction perpendicular to the cable chord line, the connecting rod allows the damper to be pushed to deform along the axis of the connecting rod, and energy consumption is reduced. When the inhaul cable vibrates in the horizontal direction perpendicular to the cable chord line, the connecting rod is allowed to rotate around the position where the connecting rod is connected with the supporting rod, and the damper is pushed to dissipate energy and reduce vibration. The inhaul cable vibration reduction system can solve the problem that the lower end of the inhaul cable is not suitable for installation of a damper for vibration reduction, and can also work in cooperation with the damper installed at the lower end of the inhaul cable, and the vibration reduction effect is improved.
本发明涉及结构工程和振动控制技术领域，尤其是涉及一种塔端安装的拉索减振系统，该包括阻尼器、支杆和连杆；连杆的顶端与拉索的中部相连接，另一个端部与阻尼器的顶端活动连接，阻尼器的底端通过承托固定于塔上；连杆的中部与支杆的底端相连接，支杆的顶端固定于塔上；支杆与塔相连接的位置高于阻尼器与塔相连接的位置；当拉索发生竖向方向垂直于索弦线的振动时，连杆允许推动阻尼器沿着连杆轴线变形耗能减耗；当拉索发生水平方向垂直于索弦线的振动时，连杆允许绕其与支杆连接的位置转动，推动阻尼器耗能减振。本发明的拉索减振系统既能够解决拉索下端不适应安装阻尼器减振的情况，也可以与拉索下端安装的阻尼器协同工作，提升减振效果。
