Cylinder structure capable of resisting fluid vortex-induced vibration
The invention discloses a novel cylinder structure capable of resisting fluid vortex-induced vibration. The cylinder structure is characterized in that the bottom end of the cylinder structure is fixed on a base, the cross sections of the cylinder structure are polygons identical in shape, and the part from one optional section of the cylinder structure to the top end of the cylinder structure forms a spiral structure through polygon rotation. The cylinder structure has the advantages that the fact that section vortex-induced force correlation attenuation is beneficial to the inhibition of vortex-induced vibration amplitude is realized sufficiently, and the sections are designed into a spiral rotating structure to allow structure vortex-induced force correlation to attenuate as fast as possible; meanwhile, the defect that a streamline structure only has good vortex-induced vibration resistance in a single direction is overcome, later maintenance is not needed basically, and cost is lowered.
