摘要
描述了用无界平面逐步分割船体内部任意有界空间,从而划分出每个舱室的计算机辅助设计方法,其关键技术是建立在数据库基础上的B-rep方法应用。提出了较完整的关于船体及其内部各种不同形状和位置的舱室几何拓扑关系的描述。解决了船体内部空间分隔具有任意性的问题,可以获得任意一个舱室或多个组合舱室的点、线和面的完整数据信息。实船的分舱设计结果证明了该方法的先进性和实用性。
A method of ship compartmentation, using an unlimited plane to subdivide the inner space of any limited temporary compartment, is presented. The key to this method is to create a complete geometrical and topological description of ship hull surface and its inner bounded spaces on the level of surface modeling. All information is stored and maintained by a relational database. The result from this process is useful for the succeeding calculation of capacity and stability. A practical program based upon this method has been realized though some imperfect even errors may exit. Its characteristic of less data input, high speed calculation and easy-to-be-modified are of significance in ship conceptual and preliminary design.
