摘　　要：为研究缓波形钢悬链立管相对于简单钢悬链立管在运动、强度及疲劳等性能方面的变化,并充分考虑与其强度及疲劳特性有关的影响因素,以进一步提升其工作的安全性,基于悬链线法和集中质量法对缓波形钢悬链立管进行静力、动力分析,利用S-N曲线法对其进行疲劳分析,将缓波形钢悬链立管动态运动计算结果、强度及疲劳特性与简单钢悬链立管进行对比,探讨总结了不同立管设计参数对其运动特性的影响规律。In order to study the specific variation of performances about motion,strength and fatigue between the lazy wave catenary riser and simple catenary riser,and fully consider the factors affecting the strength and fatigue characteristics to further ensure its working safety,the static and dynamic analyses of the lazy wave catenary riser were carried out based on catenary method and lumped mass method. The fatigue analysis was performed by using the S-N curve method,and the dynamic movement,strength and fatigue characteristics of the lazy wave catenary riser were compared with those of the simple steel catenary riser. The advantages of the lazy wave riser and the influence of the design parameters of the riser on its motion characteristics were discussed.
