摘　　要：为了设计、分析和优化一型大起重功能的桁架式自升式风电安装船的桩靴,确保桩靴按期备料、下料并开工建造,针对桩靴初始结构设计,采用中国船级社规范要求的2种加载方法,考虑预压载、偏心、正常操作以及风暴自存工况等,通过SESAM软件进行初步结构强度分析。在此基础上对桩靴结构强度进行局部加强和设计优化,对整个桩靴内部板厚、舱壁板和开孔布置等进行二次优化设计,实现桩靴优化减重,降低材料成本,保证桩靴整体结构强度和运行安全,并形成一套完整的桩靴结构设计分析及优化方法。研究成果可为自升式风电安装船桩靴结构设计方案评估及系列化设计建造提供参考。In order to analysis and optimize the spudcan design of a truss self-elevating wind power installation vessel with large lifting capacity,two loading methods required by China Classification Society(CCS)are used for the basic structural design of the spudcan,and ensure the spudcan construction firstly start to fulfill the cycle of the project.Based on the preloading,eccentric,normal operation and survival conditions,preliminary structural analysis is carried out using SESAM software.On this basis,the structural strength of pile boots is locally strengthened and optimized,Internal plate thickness,the general arrangement of inner bulkheads and hole plan are further optimized to realize reduction of weight and material cost,and the global structural strength and operation safety fulfill the requirement of the rules,and finally a complete procedure of structural design,analysis and optimization methods is formed,providing engineering reference for the evaluation of spudcan series and construction of self elevating wind power installation vessel.
