The invention relates to the technical field of ship design, in particular to a twisted longitudinal design method and a twisted longitudinal processing method.The method comprises the steps that firstly, the intersecting line of a twisted longitudinal model and a ship shell model is divided into a plurality of final curve segments; setting two adjacent final curve segments as a first curve segment and a second curve segment respectively, and connecting two ends of the first curve segment and two ends of the second curve segment to form a first straight line segment and a second straight line segment; making a first normal and a second normal of the hull shell through the first straight line segment and the second straight line segment, making a first reference plane and a second reference plane, and making a first longitudinal segment model and a second longitudinal segment model according to an intersection line of the first reference plane and the hull shell and an intersection line of the second reference plane and the hull shell; and then the end parts of the first longitudinal bone segmentation model and the second longitudinal bone model are cut off, and a twisted joint model is formed between the first longitudinal bone segmentation model and the second longitudinal bone model, so that the length of the twisted longitudinal bone model needing to be subjected to double-sided curvature processing is shortened.
本发明涉及船舶设计技术领域,特别是涉及一种扭曲纵骨设计方法及扭曲纵骨加工方法,先将扭曲纵骨模型与船体外壳模型的交线分割为多个最终曲线段;设相邻的两个最终曲线段分别为第一曲线段和第二曲线段,连接第一曲线段的两端和第二曲线段的两端作出第一直线段和第二直线段;过第一直线段和第二直线段作船体外壳的第一法线和第二法线,然后作出第一基准平面和第二基准平面,根据第一基准平面与船体外壳的交线和第二基准平面与船体外壳的交线作出第一纵骨分段模型和第二纵骨分段模型;再截去第一纵骨分段模型和第二纵骨模型的端部,再在第一纵骨分段模型和第二纵骨模型之间作扭曲接头模型,缩短了扭曲纵骨模型需要双面曲度加工的长度。
