基于大挠度柔性索理论,采用可伸长缆模型模拟钢悬链线立管(SCR)和系泊缆,同时考虑浮式结构运动的影响和钢悬链线立管与海底相互作用问题,基于Cable3D开发出浮式结构和钢悬链线立管的整体分析程序V-Cable3D。分析了Spar出平面准静态漂移引起的SCR动力效应和SCR与海底相互作用引起的疲劳应力循环。
Based on the theory of large deflection flexible cable, the scaffolding riser (SCR) and mooring line are simulated by extensible cable model. The influence of the floating structure motion and the interaction between the riser and the steel catenary are considered. Cable3D has developed the V-Cable3D, an overall analysis program for risers of floating structures and steel catenaries. The SCR dynamic effects caused by quasi-static drift of Spar plane and the fatigue stress cycle caused by the interaction between SCR and the seafloor are analyzed.
