초록

This study is related to the suppression for flow-induced vibration occurred in a circular cylinder among the
fluid flow (airstream) by using different types of flexible sheet. With free-vibration tests, the characteristics of
the vibration was experimented on the circular cylinder with flexible sheet attached, and the dependency of
suppressibility on the flow velocity was also determined. The optimal values in length and width of the different
sheets, including various shapes of triangle and strip types, and the vibration suppression mechanism and
its effect were investigated with varying the suppressor's dimensions in various patterns; the lengths are in the
range of 0.5∼3D, where D is the cylinder diameter. As results, successful works have been achieved concerning
the suppression mechanism of the vibration, the optimal shapes and sizes of various suppressors and its
suppression effect, which have not been known up to now.
