In this study, suppression of flow-induced vibration of elastically supported circular cylinder by attaching a flexible sheet was investigated experimentally. In particular, dependence on the flow velocity of flow-induced vibration characteristics of the circular cylinder attached with a flexible sheet was investigated in detail. The flexible sheet of different length (l) were attached on the cylinder surface at different angles (θ measured from back side stagnation point). The angle θ was set at five different angles, 90°, 45°, 0°, -45°and -90°. The length l of the flexible sheet was varied from 0.5to 3.0 times of the cylinder's diameter at the interval of 0.5. The width T of the flexible sheet along the span of the cylinder was also varied from 1.0L to 0.4L (L is the length of the cylinder) to find out the minimum width of the sheet to suppress the flow-induced vibration of the cylinder effectively. Furthermore, the flexible sheet of the minimum width was split into 2 to 5 pieces and attached on the cylinder, and changes in the flow-induced vibration characteristics were investigated. Also the vibration characteristics were investigated for a flexible sheet in shape of anisosceles triangle. As a result, the optimal length l of the flexible sheet was found to be 2 to 2.5 times of the cylinder's diameter, and the minimum width T of the flexible sheet to suppress the flow-induced vibration of cylinder was found to be 0.7L. Most importantly, it was found that the use of the flexible sheet suppress the vibration not only in one flow direction but also in various flow directions
