基于知识的飞行器外形设计系统研究

针对飞行器外形设计的复杂性、往复性特点,提出了基于知识的飞行器外形设计系统体系结构。利用飞行器方案设计专家系统推理的结果,开发了基于UG平台的飞行器外形设计系统,实现了飞行器外形的自动式建模和向导式建模。融合飞行器外形设计的设计规则和经验知识,设计了基于UG/KF的飞行器各部位的知识特征模型。由此设计完成的飞行器外形模型可脱离该设计系统进行修改设计,从而满足了重复设计的需要,提高了设计效率。

Research on Aerocraft Shape Design System with Knowledge Based Engineering

In allusion to satisfy the complexity and to-and-fro of aerocraft shape design,the paper issues a shape design.Based on the reason result from expert system,we have developed the aerocraft shape design system,which includes auto modeling and guide modeling.Fusion with design rules and experience knowledge,the paper issues a shape design system based on UG/KF's part knowledge model feature.Thus the design result can design renewably without considering origin model,which can satisfy the design demands,improves the veracity.
