基于CATIA二次开发的浅吃水肥大船隧道双艉型线参数化设计

在普通双隧道型艉的基础上进行变换,得到一种适合内河浅吃水肥大船的丰满的双隧道艉型。为了实现对这种隧道艉型线的快速生成,采用以隧道艉型的特征控制线为基础的方法生成隧道艉型线。各特征控制线则通过参数化的方法生成,整个过程以CATIA为开发平台,VB为开发工具,对其进行二次开发,编制隧道船艉参数化设计程序,快速生成隧道船艉的三维模型。

Parametric Design of Twin Tunnel-stern of Hypertrophic Shallow Draft Ship Using API in CATIA

By the transformation of the lines of the common twin tunnel-stern style,a modified twin tunnel-stern style which is suitable for the river full-scale shallow draft ship was achieved.In order to generate this stern style quickly in ship molded lines design,some controlling parameters to determine the shape of the stern were defined,including to the longitudinal character-controlling lines and the transverse character-controlling lines.By using CATIA as developing platform,VB as developing tools,it＇s feasible to develop the parametric design program of the modified twin tunnel-stern style so as to generate the three-dimensional model of the stern rapidly.
