The invention relates to the technical field of ship construction, and discloses a curved surface single plate type bilge keel lofting method, which comprises the following steps of: drawing a bilge keel inner opening line in a cross section view of a lofting area unit to obtain a bilge keel inner opening line in the cross section view of the lofting area unit on a ship cross section view; projecting to obtain a bilge keel inner opening line in a plane top view and a bilge keel outer opening line in the plane top view; projecting to obtain a bilge keel inner opening line in a side view and a bilge keel outer opening line in the side view; the actual length of the bilge keel inner opening line of the lofting area unit, the actual length of the bilge keel outer opening line of the lofting area unit, the expansion length of the diagonal line ad of the lofting area unit and the expansion length of the diagonal line cb of the lofting area unit are calculated, an expansion drawing of the lofting area unit is drawn, and an expansion profile drawing of the bilge keel is obtained through splicing. The whole lofting process is reserved, quality tracing, improvement and inspection of the bilge keel manufacturing process are facilitated, and the manufacturing quality of the bilge keel is improved.

    本发明涉及船舶建造技术领域,公开了一种曲面单板式舭龙骨的放样方法,通过放样区域单元的横剖视图中的舭龙骨内口线绘制得到在船舶横剖视图上获取放样区域单元的横剖视图中的舭龙骨内口线;投影得到平面俯视图中的舭龙骨内口线与平面俯视图中的舭龙骨外口线;投影得到侧视图中的舭龙骨内口线与侧视图中的舭龙骨外口线;计算放样区域单元的舭龙骨内口线的实际长度、放样区域单元的舭龙骨外口线的实际长度、放样区域单元的对角线ad的展开长度和放样区域单元的对角线cb的展开长度,绘制放样区域单元的展开图,通过拼接得到舭龙骨的展开轮廓图。本发明保留整个放样过程,方便对舭龙骨制作过程质量追溯、改进与检验,提升舭龙骨的制作质量。
