The invention belongs to the technical field of ship body molded line lofting and fairing, and discloses a lofting method for a stern molded line containing pod prosthesis which comprises the following steps: obtaining a fairing stern molded line graph according to an original ship body molded line graph; according to the original pod prosthesis design module, obtaining a theoretical pod prosthesis profile; covering the theoretical pod prosthesis molded line into the fairing stern molded line graph to obtain a space line, and fairing to obtain a boundary line; obtaining a shear pod prosthesis profile according to the boundary line and the theoretical pod prosthesis profile, and then performing fairing treatment to obtain a fairing pod prosthesis profile; obtaining a stern molded line without a pod prosthesis according to the boundary line and the fairing stern molded line; and splicing the fairing pod prosthesis molded line and the stern molded line without the pod prosthesis to obtain a stern molded line graph containing the pod prosthesis. The stern molded line and the pod prosthesis molded line are defined in a database for fairing treatment, so that ship design software can be adopted for fairing treatment, and the lofting efficiency of the pod prosthesis molded line is improved by determining a boundary line.

    本发明属于船体型线放样光顺技术领域,公开一种包含吊舱假体的艉部型线的放样方法,包括步骤:根据原始船体型线图,得到光顺艉部型线图;根据原始吊舱假体设计模块,得到理论吊舱假体型线;将理论吊舱假体型线覆盖到光顺艉部型线图中,得到空间线,再光顺处理得到边界线;根据边界线和理论吊舱假体型线得到剪切吊舱假体型线,再光顺处理得到光顺吊舱假体型线;根据边界线和光顺艉部型线得到不含吊舱假体的艉部型线;将光顺吊舱假体型线和不含吊舱假体的艉部型线拼接,得到包含吊舱假体的艉部型线图。将艉部型线和吊舱假体型线分别定义数据库进行光顺处理,从而都能采用船舶设计软件进行,通过确定边界线来提高吊舱假体型线的放样效率。
