  • 摘要:
    目的 针对长江航运航行环境复杂，部分船型能耗大、污染严重，迫切需要开展绿色智能船型研究的现状，将知识图谱应用到型线设计方法中，以适应绿色智能技术发展对船型优化的要求。
    方法 构建长江货船型线知识图谱及推理模型，提出基于知识图谱的型线设计流程，完成长江6 000吨级散货船型线的快速设计，并与常规方法设计的船型进行对比。
    结果 与常规设计船型的对比结果表明，快速设计船型具有2.39%的降阻效果。
    结论 验证了基于知识图谱的型线设计方法的有效性。

     

    Abstract:
    Objective Aiming at the complexity of the navigation environment of the Yangtze River shipping, the high energy consumption and serious pollution of some ship types, there is an urgent need to carry out the research on green and intelligent ship types, and the knowledge graph is applied to the hull form design method to adapt to the requirements of the development of the green and intelligent technology on the optimization of the ship types.
    Methods The knowledge graph and inference model of Yangtze River cargo ship hull form are introduced, and a knowledge graph-based hull form design process is proposed for the first time to complete the rapid design of an excellent hull form for a 6 000 t bulk carrier of the Yangtze River and compare it with that of the ship designed by conventional methods.
    Results Drag reduction effect of 2.39% was obtained compared with the conventional design ship type.
    Conclusion The effectiveness of the knowledge graph-based hull form design method was verified.
