The invention relates to a ship subdivision design method based on concept optimization, and belongs to the technical field of ship design and manufacturing. According to the method, the longitudinal position of each section of transverse bulkhead and the proportion of the cargo hold, the ballast tank and the void tank in the cargo hold section in the cargo hold volume are used as optimization variables, the minimum ship body beam still water bending moment extreme value is used as a target function, and the requirements of each specification criterion and the division principle facilitating cargo loading and unloading and empty ship weight reduction are used as constraint conditions; and carrying out subdivision optimization by adopting an optimization algorithm. The design method based on concept optimization is provided for ship subdivision design, and more reasonable subdivision can be provided according to ship type characteristics, ship owner requirements and standard rule requirements of each ship. The structure size of the ship is effectively controlled, and the economical efficiency and the environmental protection property of the ship are improved; according to the method, the requirement on professional skills of designers is reduced, and the labor cost of enterprises can be reduced.
本发明涉及一种基于概念优化的船舶分舱设计方法,属于船舶设计及制造技术领域。本发明将各段横舱壁的纵向位置以及货舱段内货舱、压载舱和空舱所占货仓容积的比例作为优化变量,以船体梁静水弯矩极值最小作为目标函数,以各规范准则的要求及有利于货物装卸和减轻空船重量的划分原则为约束条件,采用优化算法进行分舱优化。通过本发明为船舶分舱设计提供了一种基于概念优化的设计方法,可根据每一条船的船型特点、船东要求及规范规则要求,提供更为合理的分舱。使船体梁静水弯矩尽可能小,有效控制船舶结构尺寸,提高船舶经济性及绿色环保性;通过本发明降低了对设计人员专业技能的要求,可降低企业用工成本。
