摘　　要：在船型概念设计阶段,基于船舶阻力图谱进行船舶快速性分析是一种高效便捷的方式.由于远洋鱿鱼钓船船型方案设计缺少专用船舶阻力图谱,研究了适用于远洋鱿鱼钓船的阻力图谱开发方法、步骤和基于图谱的航速预报.以66 m远洋鱿鱼钓船为母型船,基于宽度和吃水比将变换船型分成两大系列,再根据排水体积长度比,将每个大系列进一步细化成3个小系列作为目标船型进行研究,建立了母型船三维模型及其系列派生船型.基于Star-CCM+软件的重叠网格方法,对系列船型阻力进行数值模拟,将阻力计算结果通过二因次法换算为15℃海水下实船阻力及对应有效功率系数,绘制远洋鱿鱼钓船阻力图谱.利用该图谱估算母型船阻力并与船模试验结果进行对比,证明了远洋鱿鱼钓船阻力图谱具有较高精度,可用于远洋鱿鱼钓船概念设计和方案优化设计.Using ship resistance diagrams to analyze ship rapidity is an efficient and convenient way during the conceptual design phase of a ship.As there is no specific ship resistance diagrams for the design of ocean-going squid fishing ship,the development methods and procedures of resistance diagrams and speed prediction based on diagrams are studied for ocean-going squid fishing ship.Taking the 66 m ocean-going squid fishing ship as the mother ship,two large series are provided for the transformed ships based on the width and draft ratio.According to the drainage volume to length ratio,each large series is further refined into three small series as the target ship type.A 3D model of the mother ship and a series of derived ship types are established.Based on overlapping grid method of the Star-CCM+software,the numerical simulation of the resistance of the series of ships is carried out,and the results of the resistance calculation are converted into the resistance and the corresponding effective power coefficient of the real ship under 15℃of sea water by the two-factor method,and the resistance diagrams of the ocean-going squid fishing ship are drawn.The resistance results of the mother ship predicted by the diagrams are compared with the experimental results of the ship model,and it is proved that the resistance diagrams of ocean-going squid fishing ship are of high accuracy,and can be used for the conceptual design of ocean-going squid fishing ship and the optimization design of the scheme.
