Device capable of inhibiting vortex-induced vibration of open caisson
The invention discloses a device capable of restraining vortex-induced vibration of an open caisson structure. The device comprises a round-end-shaped open caisson and spiral pattern flow guide plates, the spiral pattern flow guide plates are cylinders with the length of 5.66 m, the width of 2.74 m, the height of 15 m and the area ratio of 100%, and the spiral pattern flow guide plates are arranged on the two sides of the round-end-shaped open caisson by inclining by 45 degrees; the spiral pattern guide plate is provided with spiral patterns, and the coverage rate of the spiral patterns is not lower than 80%, so that the vortex is guided and released, and the spatial correlation and pressure field distribution of the vortex are destroyed. According to the device capable of effectively restraining the vortex-induced vibration of the open caisson, on the basis that the material strength and the dynamic stability are met, the vortex is guided and released better, the spatial correlation and pressure field distribution of the vortex are damaged, the manufacturability is high, manufacturing is convenient, and the structure is reasonable.
本发明公开了一种能够抑制沉井结构涡激振动的装置，其包括圆端形沉井、螺旋花纹导流板，螺旋花纹导流板为长5.66m、宽2.74m、高15m、面积比100％的柱体，倾斜45°设置于圆端形沉井两侧；螺旋花纹导流板上设有螺旋花纹且其覆盖率不低于80％，使得对涡旋进行引导释放，破坏涡旋的空间相关性和压力场分布。本发明提供的能够有效抑制沉井涡激振动的装置，在满足材料强度及动力学稳定性的基础上，更好地对涡旋引导释放，破坏涡旋的空间相关性和压力场分布，且工艺性高，制作方便，结构合理。
