| 摘 要： | 基于大挠度柔性索理论,采用可曲线梁模型模拟钢悬链线立管,考虑触地点挠度的影响,对CABLE3D程序进行了二次开发.同时考虑浮式结构运动和钢悬链线立管与海底相互作用问题,分析了Spar平台静态偏移引起的钢悬链线立管静态位形、顶张力、触地点弯矩以及挠度影响下节点有效张力的变化趋势.分析表明:浮体运动将引起立管顶张力和触地点...

| Abstract: | The steel catenary riser(SCR) has been simulated with an extensible flexibility cable model based on the assumption of a large deformation in bending and small extension.The program considering large curve at Touch Down Point(TDP) of SCR CABLE3D is improved secondly.Taking the factors of Spar motion and soil interaction into account,this paper focuses on the variation tendency of a few characteristic values affected by the SCR from Spar static offset,including static configuration,top tension,bending moment... |
