DYNAMIC RESPONSE ANALYSIS FOR COUPLED PARAMETRIC VIBRATION AND VORTEX-INDUCED VIBRATION OF TOP-TENSIONED RISER IN DEEP-SEA

  • 摘要: 该文研究顶张力立管参激-涡激耦合振动计算方法和动力特性。考虑立管顶端动边界条件,建立顶张力立管模型,研究其在剪切流中的涡激振动响应和参激-涡激耦合振动响应。提出立管的动力响应分析方法,分析参数激励对立管横向涡激振动的影响。结果表明,立管的横向振动响应频率存在0.5倍参激亚谐成分,参数激励对于立管横向振动具有重要影响。
    Abstract: The calculation method and dynamic characteristics of coupled parametric excitation and vortex excitation are investigated for top-tensioned risers. The analysis model of TTRs is presented considering the moving boundary conditions, and the vortex-induced response, coupled parametric excitation and vortex excitation vibration of TTRs in the shear flow are studied. The analysis method of dynamic response is proposed to research the influence of parametric excitation on VIV of the TTRs. The result shows that the VIV response of the TTRs contains the component of 1/2 sub-harmonic induced by parametric excitation, and that the parametric excitation has important significant for transverse vibration of TTRs.
