摘　　要：基于钢悬链线立管系统动力学方程,建立了深水钢悬链线立管三维有限元分析模型,对深水钢悬链线立管系统在波浪、海流和浮体运动等载荷单独作用和共同作用下的响应特征进行了分析。在多项载荷作用下,钢悬链线立管表现出明显的平面外响应,并且响应具有非线性特征,立管上部悬挂点和底部着地点附近M ises应力较高,是立管的危险段。A three-dimensional finite element analysis model of deepwater SCR is built based on the dynamic equations of SCR.Responses of SCR system under wave,current and floater motions separately and assembly are simulated and analyzed.It can be concluded that SCR has responses out of the SCR plane which are nonlinear in case of multi-loads.The Mises stress in place near the SCR hang-off point and touch-down point are high,the corresponding parts are risky and should be paid more attention to them.
