摘要
选取某近海小型渔政船典型船型,研究艏艉线型和附体对船舶阻力性能的影响。通过对线型、船型系数以及舭龙骨、压浪板、呆木等常规附体对小型渔政船航行性能的影响进行数值模拟分析,优化船舶线型,针对小型渔政船的功能需求选取合适的附体组合形式,并通过实船运行验证优化后的渔政船航行性能有所改善,达到预期目标,可为同型船舶设计提供参考依据。
The typical ship type of a small offshore fishery ship is selected to study the influence of the ship rifling type and attached body on the ship resistance performance.Through the numerical simulation analysis of the hull line type,the ship type coefficient and the influence of the conventional body such as bilge keel,spray strip and dead wood on the navigation performance of the small fishery ship,the ship line type is optimized,and the functional requirements of the small fishery ship are selected.The combination of the attached body and the improved performance of the fishery ship after the actual ship operation verification improve the expected target and can provide a reference for the design of the same type of ship.
