摘　　要：本文以某80000吨级散货船为优化对象,应用基于融合和区域特征分析的两种新船型几何设计技术,结合船舶CFD阻力和自航评估技术,开展以设计吃水下快速性能为目标的船型设计和性能分析研究。整个设计过程以参考船为设计起点,从减小船体阻力、改善兴波和艉部伴流的角度入手,分别开展船型艏部和艉部的型线自动变形设计,对比分析改型方案在同一模型尺度下的CFD数值模拟评估结果,并获得快速性能优秀的船型设计方案。最后,通过静水中的快速性模型试验,对设计工况下的收益效果进行验证,结果表明,相比于设计原型,最终优化船型在航速为14.0 kn时的实船预报收到功率下降了约5.6%。With an 80000 DWT bulk carrier taken as the optimization object,two new hull lines design tech⁃nologies based on the hull fusion method and regional feature analysis were applied by combining ship CFD resistance and self-propulsion assessment for the research on hull lines design and performance analysis,aiming at the hydrodynamic performance under design draft.With the whole design process starting with the reference ship,the hull line automatic deformation designs of the bow and stern part were made respectively in order to reduce the resistance and improve the wave making and stern wake distribution.By analyzing the CFD numerical simulation evaluation results under the same model scale,a series of design hulls with good performance were successfully obtained.Finally,the simulation results were verified by model test under the design draft in still water.Compared with the design prototype,the received power trial prediction of the final design scheme at the speed of 14.0 kn was reduced by about 5.6%.
