The invention relates to the field of bridge engineering, and particularly discloses a vortex-induced vibration controller which comprises a connecting device and a control device. The control devicecomprises an outer shell, a cavity is formed in the outer shell, mounting holes are formed in the two sides of the outer shell and connected with the cavity, elastic pieces are arranged in the mounting holes in a sliding mode, elastic surrounding rods are arranged at the bottoms of the elastic pieces, choke cloth is arranged in the surrounding rods, a plurality of elastic pieces are arranged in the cavity, and the two ends of each elastic piece are connected with the two opposite elastic pieces respectively. A rotating shaft is further arranged in the cavity, a plurality of first steel ropes are wound on the rotating shaft, and the first steel ropes are connected with the adjacent elastic pieces; a vertical hole is formed in the top of the outer shell, a hollow control rod is arranged at the top of the vertical hole, a thin-wall piece with the wall thickness smaller than that of the control rod is integrally formed at the top of the control rod and connected with the bottom of a bridge, a second steel rope is fixedly arranged on the rotating shaft, the second steel rope is tensioned, and the upper end of the second steel rope is connected with the top of the thin-wall piece. The controller aims to solve a technical problem of vortex-induced vibration of the bridge.
本发明涉及桥梁工程领域，具体公开了涡激振动控制器，包括连接装置以及控制装置；控制装置包括外壳体，外壳体内设有空腔，外壳体的两侧设有安装孔，安装孔与空腔连通，安装孔中滑动设有弹片，弹片的底部设置有具有弹性的围杆，围杆中设置有阻风布，空腔中设置有若干弹性件，弹性件的两端分别与相对的两个弹片连接；空腔内还设有转轴，转轴上缠绕有若干第一钢绳，第一钢绳与相邻的弹片连接；外壳体的顶部开设有竖孔，竖孔的顶部设置有内部中空的控制杆，控制杆的顶部一体成型有壁厚小于控制杆的薄壁片，薄壁片与桥梁底部连接，转轴上固定设有第二钢绳，第二钢绳张紧且其上端与薄壁片的顶部连接。本发明的目的在于解决桥梁涡激振动的技术问题。
