| 摘 要： | 由于浮式平台升沉运动的影响,导致立管在水平方向上发生参激振动。参激振动可以引起立管平衡位置的不稳定性,此外,参激振动与涡激振动联合作用会改变立管振动响应特性,加剧立管疲劳破坏。为对深海立管参激振动进行深入研究,通过总结国内外立管参激振动研究的主要成果,介绍了立管参激振动的主要特点和动力学模型,归纳了深海立管参激振动研究的主要方向,并就研究中较为薄弱的一些环节,提出了一些建议。

| Abstract: | A transverse riser vibration called parametric vibration is caused by the heave of a floating platform. Parametric vibration might destabilize the straight equilibrium of the riser and cause it to vibrate at a dangerously high level. In addition, the dynamic response and fatigue life of the riser will be changed due to coupled vibration of parameter vibration and vortex-induced vibration. It is necessary to pay much attention to parametric vibration analysis of deep-water risers, for the design, safety and dynamic optimization of risers. This paper presents the related studies and achievements in recent years. The suggestions for further studies in this field are made as well. |
