The invention provides a design method of a ship bow workpiece and a ship, and the design method comprises the steps: S1, expressing the structure of a ship bow through a transverse section, a longitudinal section and a horizontal section, and determining the structural line type of the ship bow; s2, establishing an operation reference for judging narrow space construction of the ship bow; s3, determining boundaries belonging to the narrow space in the cross section and the horizontal section; s4, determining an intersection point of the boundary and the hull plate, and determining a spline curve of the workpiece according to the intersection point; and S5, establishing a hollowing reference in the workpiece according to the spline curve, hollowing the interior of the workpiece, and completing the design of the workpiece. The ship bow part workpiece manufactured through the design method meets the double standards of structural light weight and structural strength at the same time, and particularly for the situation that the ship bow part workpiece is a steel casting, the weight of the ship bow part is greatly reduced, the transportation cost of the ship is reduced, and the transportation efficiency of the ship is improved.
本申请提供了一种船舶艏部工件的设计方法及船舶,设计方法包括:S1:分别以横剖面、纵剖面、水平剖面对船舶艏部的结构进行表达,确定船舶艏部的结构线型;S2:建立判别船舶艏部狭小空间施工的作业基准;S3:确定横剖面和水平剖面中属于狭小空间的边界;S4:确定边界与船体外板的相交点,根据相交点确定工件的样条曲线;S5:根据样条曲线建立工件内部的挖空基准,对工件内部进行挖空,完成工件的设计。通过本申请设计方法制造的船舶艏部工件同时满足结构轻量化和结构强度双重标准,尤其是针对船舶艏部工件为铸钢件的情况,极大的减轻了船舶艏部的重量,降低了船舶的运输成本,提升了船舶运输效能。
