摘　　要：为研究完整稳性衡准对某新型远洋围网渔船船型设计的影响,提高远洋围网渔船方案设计初期的决策效率,以20 m、30 m、40 m级等3条同类型不同尺度范围的远洋围网渔船为样本库,利用NAPA软件进行船型仿射变换生成系列新船型,并对新船型进行完整稳性校核计算,分析船长、型宽型深比、立方数和鱼舱容积系数等船型参数的变化对船舶完整稳性的影响趋势。建立以完整稳性衡准限值要求为约束条件的新型远洋围网渔船船型要素数学模型,通过计算实例验证了回归模型的可行性和有效性,形成了新型远洋围网渔船方案设计初期快捷有效的决策方法,为远洋渔船船型设计研发和渔船安全理论的研究提供有效技术支撑。In order to study the influence of integrity stability criterion on the ship type design of a new type of ocean Seine fishing vessel and improve the decision-making efficiency in the early stage of scheme design of ocean Seine fishing vessel,taking three ocean Seine fishing vessels of the same type and different scale ranges of 20 m,30 m and 40 m as the sample library,the ship type affine transformation is carried out by Napa software to generate a series of new ship types,the integrity stability check calculation is carried out for the new ship type,and the captain,shape width depth ratio.The influence trend of ship type parameters such as cubic number and fish tank volume coefficient on the integrity and stability of the ship,and then establish the mathematical model of ship type elements of the new ocean going purse seine fishing vessel with the requirements of integrity and stability criteria as constraints.The feasibility and effectiveness of the regression model are verified through calculation examples,and a fast and effective decision-making method in the early stage of the scheme design of the new ocean going purse seine fishing vessel is formed,It provides effective technical support for the research and development of ship type design of ocean going fishing vessels and the research of fishing vessel safety theory.
