摘　　要：以低速肥大型船的线型优化为研究对象,针对部分关键问题进行深入研究。将近似模型方法应用于船型优化工作,以使用有限数量的高精度CFD计算结果建立的近似模型来代替优化过程中复杂耗时的CFD数值计算,利用团队开发的船舶水动力性能多学科综合优化平台完成载重46000 t油船的线型优化,并进行验证。By taking the line type optimization of low speed full ship as the research object,some key issues are deeply researched.The approximate model method is applied to the hull form optimization,the complex and time consuming CFD numerical calculation in the optimization process is replaced by the approximate model established with a limited number of high precision CFD calculation results,and the multidisciplinary comprehensive optimization platform for marine hydrodynamic performance developed by the team is used to complete and verify the line type optimization of deadweight tonnage 46000 t oil tanker.
