An Experimental Study of Dynamic Response of a Top Tensioned Riser Model Subject to VIV

摘要：

　　Dynamic response of a vertical flexible cylinder vibrating at low mode numbers with combined x-y motion is investigated in this paper.The uniform flow was simulated by towing the flexible cylinder along the tank in still water;therefore the turbulence intensity of the free flow is negligible in order to obtain more reliable results.The dominant frequencies, maximum attainable amplitude, modal analysis and x-y trajectory in cross-flow and in-line directions have been reported and compared with literatures, some good agreements and justifiable discrepancies are obtained.These results could benefit the future experimental and numerical work in this area.
