船体结构CAD技术研究

Research of Hull Structure CAD Technique

分析了国内外CAD技术在船体结构设计中应用和研究的现状 ,介绍了自主研发的基于面向对象的船体结构三维建模系统 ,描述了该系统的设计思想 ,对一些技术做了探索和研究。通过可视化界面 ,自顶向下地构造出船体不同类型的结构模型 。

This paper analyses the present situation of the application and research of CAD technique for designing hull structure at home and abroad. It also introduces a 3D hull structure modeling system which is based on Object Oriented technique and developed independently, and describes design ideas of this system. Some related techniques are explored in the paper. With a visual interface, different kinds of hull structure models are constructed through the Top-Down method. The intelligentized system satisfies the requirements of optimization for hull structure design.
