Zusammenfassung:The utility model discloses a vortex-induced vibration resistant wind power tower drum in the technical field of wind power generation, which comprises a drum body and a plurality of groups of turbulent flow damping parts arranged on the outer wall of the drum body, each turbulent flow damping part comprises a longitudinally arranged barrel-shaped pipe and a transversely arranged flow guide pipe, the opening of the barrel-shaped pipe is upward, the flow guide pipe is provided with a through hole communicated with the barrel-shaped pipe, and the through hole is communicated with the barrel-shaped pipe. And the barrel-shaped pipe is filled with liquid. According to the scheme, air flow vortexes around the barrel are broken into small vortexes by the turbulent flow damping pieces, the pressure difference between the windward side and the leeward side of the barrel is reduced, and then vortex-induced loads on the two sides of the barrel are greatly reduced, so that vortex-induced vibration is reduced, the good vo
