| 摘 要： | 针对钢悬链式深海立管的特点,采用简化后的振动模型,结合圆柱体的受迫振荡实验数据,建立了深海立管在剪切流来流中的涡激振动响应分析模型。被激起的各阶模态的响应位移可通过平衡立管升力的输入能量和阻尼的耗散能量计算得到。计算结果与涡激振动专用分析软件计算结果进行了对比,吻合良好。 |

| Abstract: | According to the characteristic of the deep-water steel catenary riser,a model is presented to predict the response of vortex-induced vibration（VIV） in sheared flow based on the dates from tests with cylinders.The displacement of each excited mode is determined by a balance between the energy fed into the riser by lift force and the energy dissipated by damping.The analytical results match the results calculated by VIV professional software well. |
| Keywords: | deep-water riser steel catenary riser vortex-induced vibration lift force damping |
