The present invention relates to a vortex induced vibration reduction apparatus, comprising: a body rotatably installed on an outer surface of a structure by movement of a fluid; a wing installed on an outer circumferential surface of the body; and a support member installed between an inner circumferential surface of the body and the outer circumferential surface of the structure, and supporting the body to rotate. Accordingly, the vortex induced vibration reduction apparatus is installed in the structure to increase the entire cross section area to which power of wind or fluids such as ocean currents is applied, and thus vortex induced vibration applied to the structure can be reduced.

    와류기 진동 저검장치에 관한 것으로, 구조물의 외면에 유체의 이동에 의해 회전 가능하게 설치되는 바디, 상기 바디의 외주면에 설치되는 날개 및 상기 바디의 내주면과 구조물의 외주면 사이에 설치되고 상기 바디를 회전 가능하게 지지하는 지지부재를 포함하는 구성을 마련하여, 원통 형상의 와류기 진동 저감장치를 구조물에 설치해서 바람이나 해류와 같은 유체의 힘이 작용하는 전체 단면적을 증가시킴으로써, 구조물에 작용하는 와류기 진동을 저감할 수 있다.
