Wind vibration control device for steel pipe component of steel pipe tower
The invention provides a wind vibration control device for a steel pipe component of a steel pipe tower. The wind vibration control device is arranged outside a circular section steel pipe component in a sleeving manner. The wind vibration control device comprises a cylindrical sleeve and spoilers. The spoilers are flexible components. The cylindrical sleeve is arranged on the circular section steel pipe component in a sleeving manner. One end of each spoiler is fixedly connected to the outer surface of the cylindrical sleeve along the axial direction of the cylindrical sleeve. On a basis of afundamental principle of changing a dynamic shape, the spoilers can play roles of disturbing vortex formation and inhibiting vortex-induced vibration of the circular section component. The wind vibration control device is clear in principle and high in practicality.
本发明提供了一种钢管塔钢管构件风振控制装置，所述风振控制装置套在圆截面钢管构件外，包括：柱形套筒和扰流条；所述扰流条为柔性构件；所述柱形套筒套在所述圆截面钢管构件上；所述扰流条的一端沿所述柱形套筒的轴向固定连接于所述柱形套筒的外表面上。本发明装置基于改变气动外形的基本原理，扰流条可以起到扰乱旋涡形成、抑制圆截面构件涡激振动的作用，原理清晰，实用性强。
