This paper reports the experimental results of vortex-induced vibration of a catenary flexible riser hinged underneath a two-degree-of-freedom vortex-induced moving platform. The in-plane and out-of-plane responses of the riser are monitored by high-speed cameras while the cross-flow and in-line motions are recorded by laser displacement sensors. The strong and weak couplings between the platform motion and riser vibration are identified. Moreover, the strong coupling is further classified into two types: riser vibration dominated and platform motion dominated ones. The in-plane and out-of-plane responses of the riser also present the interaction which varies along the span. Affected by the in-line motion of the top platform, the interaction between in-plane and out-of-plane responses is weakened. Because of the spatial frequency competition, the number of required samples for machine learning varies along the riser. The maximum required number occurs in the middle part, followed by the top part as a result of the platform motion., authors=ZHU Hongjun, LIU Wenli, SONG Jinze, GAO Yue, authorsList=ZHU Hongjun, LIU

articleAbstract=悬链线型柔性立管在涡激振动与平台涡激运动的耦联作用下，存在潜在疲劳失效风险。采用高速摄像机非介入式监测了柔性立管的平面内与平面外振动位移，并利用激光位移传感器同步测量了上部平台的横荡和纵荡位移。实验判别了平台运动与立管振动的强耦联和弱耦联，其中，强耦联又分为立管振动主导和平台运动主导2种。立管平面内与平面外的振动本身存在耦合效应，其耦合强度有明显的时空变化。受平台纵荡的影响，立管上部的平面内、平面外振动出现解耦现象。由于立管振动空间上存在频率竞争，基于机器学习预测不同位置振动所需的样本数不同，频率竞争剧烈的立管中部所需样本数最多，其次是受到平台运动影响的上部管段。,
