摘　　要：针对浮式生产储卸油轮(FPSO)生活楼模块整体吊装安全需求,开展FPSO生活楼模块整体吊装过程中吊排结构型式与强度优化设计研究。基于板式吊排结构强度校核理论,利用有限元分析软件ABAQUS参数化建模对吊排强度进行分析,提出吊排结构优化流程;通过迭代计算,对不同承载能力的吊排结构进行优化定型。研究结果表明:优化定型后的吊排结构质量小于原始结构质量,在结构强度允许范围内,实现了整体结构的轻量化,研究结果可为整体式吊排结构设计提供一定参考。In order to meet the overall lifting safety requirements of the floating production storage and offloading(FPSO)living quarter module,a study on the structural type and strength optimization design of the overall lifting lug during the FPSO living quarter module lifting process is conducted.Initially,based on the strength verification theory of the plate-type lifing lug structure,parametric modeling is used to analyze the strength of the lifting lug by the finite element analysis software ABAQUS,and an optimization process for the lug structure is proposed.Through iterative calculations,the lifting lug structures with different load-carrying capacities are optimized and finalized.The research findings indicate that the quality of the optimized and finalized suspension structure is lower than that of the original structure,achieving lightweighting of the overall structure within the allowable range of structural strength.The research results can provide some reference for the design of the integral lifting lug structures.
