The invention relates to the technical field of ship body molded line lofting and fairing, and discloses a lofting method for a stern molded line containing a shaft wrapper sheet, which comprises the following steps: independently lofting and fairing a stern main ship body molded line, and drawing a theoretical shaft wrapper sheet molded line on the basis of a stern rib molded line graph obtained after lofting, and meanwhile, adding auxiliary lines and tangent point lines according to the curve characteristics of the axle cladding plate, a space curve for controlling the appearance characteristics of the axle cladding plate is smoothed in advance, and internal rib type smoothing is carried out after the basic outline of the axle cladding plate is determined. According to the lofting method for the stern molded line containing the shaft wrapping plate, the lofting working difficulty is reduced while the lofting precision is guaranteed, the lofting working efficiency is improved, and basic conditions are provided for follow-up lofting and modeling work of the shaft wrapping plate.

    本发明涉及船体型线放样光顺技术领域,公开了一种含轴包板的艉部型线的放样方法,通过对艉部主船体型线先行单独进行放样光顺,再以放样后得到的艉部肋骨型线图为基础绘制出理论轴包板型线,同时根据轴包板曲线特征增加辅助线、切点线,提前对控制轴包板外形特征的空间曲线进行光顺,确定轴包板基本轮廓后再进行内部肋骨型光顺。这一种含轴包板的艉部型线的放样方法在保证放样精度的同时降低了放样工作难度,提高了放样工作效率,为后续轴包板放样及建模工作的提供了基础条件。
