Process examination system of aircraft sheet metal parts based on KBE
-
摘要: 由于板金零件的可成形性取决于多方面的因素,板金零件成形的工艺性审查也就显得十分复杂,工艺审查的合理性和准确性往往成为飞机设计和制造的矛盾焦点.通过分析当前我国飞机板金零件工艺性审查的现状,提出了在工艺性审查中利用基于知识的(KBE,Knowledge Based Engineering)技术的必要性.分析了利用后台数据库及知识库创建工艺性审查系统的总体结构和实现方案,并对系统创建中的关键技术及解决方法进行了研究.通过实例验证了该系统的功能及可靠性.Abstract: Because the sheet formability rests with various factors, the process examination of sheet metal parts is very complicated. The scientificity, rationality, veracity and reliability of process examination are the main factors in the aircraft design and manufacture. The importance of using the knowledge based engineering(KBE) technology in the process examination was put forward by means of analyzing the actuality of process examination for aircraft sheet metal parts. The general structure and realizing scheme of the process examination system were analyzed based on the database and knowledge base, and the key techniques and solution methods were studied during establishing this system. According to the example, the reliability and the function of the system were justified.
