摘　　要：以某海况的陡波线型设计为研究对象,以水面浮体的漂移域、管道线型最大曲率和经济性为设计指标,建立柔性立管整体线型的数值分析模型,开展这3项指标对于浮筒设计数量的灵敏度分析。提取上述指标结果,进行归一化处理,以漂移域最小、线型曲率最大、经济成本最低为优化目标,进行具有陡波线型特征的柔性立管系统浮筒数量的多目标优化设计,给出最优设计方案。A steep wave configuration design is taken as the research object,the drift domain of the floating body on the ocean surface,the maximum curvature of the pipeline and the economy are taken as the design indexes.The numerical model of the flexible riser configuration is established,and the sensitivity of the three indexes to the number of buoyancy modules is analyzed.The minimum drift domain,maximum configuration curvature and minimum cost are extracted as the optimization objectives with the normalization processing.The multi-objective optimization design of the number of buoyancy modules of the flexible riser with steep wave configuration is conducted and the best design is obtained.
