The invention relates to the technical field of ship construction, in particular to a stern shaft tube intersecting line drawing method and a stern shaft tube, and during stern shaft tube intersecting line drawing, a neutral layer of the stern shaft tube is determined firstly, a plurality of marking lines are arranged around the neutral layer at intervals, and a side view of the neutral layer is drawn on CAD software; drawing an unfolded plane graph of the neutral layer above or below the side view of the neutral layer; corresponding longitudinal molded lines of the ship planking are extracted from the CAD molded line graph of the ship planking, and the longitudinal molded lines are copied to the side view of the neutral layer; taking the intersection point of each longitudinal molded line and the corresponding identification line as a starting point, and making a first projection line towards the unfolded plane graph of the neutral layer; sequentially connecting the intersection points of the first projection lines and the corresponding identification lines in the expansion plane graph of the neutral layer to form an intersecting line expansion line of the first end of the stern shaft tube; the intersecting line expansion line of the first end of the stern shaft tube can be drawn by using the two-dimensional diagram of the longitudinal molded line of the ship outer plate, so that the stern shaft tube and other parts can be processed in parallel.

    本发明涉及船舶建造技术领域,特别是涉及一种艉轴管相贯线绘制方法及艉轴管,艉轴管相贯线绘制时,先确定艉轴管的中性层,环绕中性层间隔设置多个标识线,在CAD软件上绘制中性层的侧视图;然后在中性层的侧视图的上方或下方绘制中性层的展开平面图;再从船舶外板的CAD型线图中提取对应的船舶外板的纵向型线,将各纵向型线复制至中性层的侧视图中;然后以各纵向型线与对应的标识线的交点为起点,向中性层的展开平面图作第一投影线;将各第一投影线与中性层的展开平面图中对应的标识线的交点依次连接形成艉轴管的第一端的相贯线展开线;利用船舶外板纵向型线的二维图即可作出艉轴管的第一端的相贯线展开线,使得艉轴管能够与其他部件并行加工。
