基于知识工程的钣金快速工艺设计系统开发

摘要

Actual rapid development needs of domestic and foreign modem civil aircraft are described.Referencing experience of foreign aviation manufacturing enterprises and domestic aircraft sheet metal progress,overall methods and ways of rapid sheet metal process design system are built,and taking knowledge engineering technology as the core,numerical reasoning as means.Rapid sheet metal design process system is established by expert knowledge building and system software development.Process analysis and design of sheet metal parts are realized in bulk and automatically;Process analysis reports,manufacturing outline,NC code are automatically generated,which can greatly increase process design efficiency of civil aircraft development and reduce labor.%介绍了国内外现代民用飞机快速研制的实际需求,参考国外航空制造企业的经验和国内飞机钣金专业技术在知识工程方面的研究进展,提出了以知识工程技术为核心,以数值推理为手段,建立钣金快速工艺设计系统的总体思路与技术途径,并通过专家知识库构建和系统软件开发,建立基于知识工程的钣金快速工艺设计系统.通过在民用飞机研制中的应用,批量、自动实现了钣金零件的工艺性分析、工序设计,自动生成工艺分析报告、制造大纲、数控代码,大幅度提高民用飞机研制的工艺设计效率,降低技术人员的劳动强度.
