摘要: 为了配合航空工业进一步技术更新,以信息化技术提升传统的飞机板金成形工艺,根据航空工业飞机生产、型号预研、板金成形工艺手册、工艺实验等大量信息数据,以Oracle数据库作为后台的支撑数据库,应用面向对象的Visual C+ +.NET作为前台开发工具,研究开发了一套基于实例的飞机板金工艺知识库系统,该系统建立了统一的工艺实例信息模型,以工艺实例作为基本信息单元,涵盖大量的成形工艺、工装模具等数据信息,具有知识维护、知识匹配和知识修正等功能.本文还对该系统的体系结构、实现方法及关键技术进行了分析.

Abstract: To promote further technological innovation for aeronautic industry and improve the conventional aircraft sheet metal forming process with information technology, a system of case-based knowledge base for aircraft sheet metal forming was developed by using Oracle database management system and Visual C+ +.NET. It is based upon a great deal of data and information from the aircraft manufacturing, pre-research, sheet metal forming manual and process tests in aeronautic industry. This system establishes a uniform information model of process cases as elementary cells of information. It includes a lot of data and information about forming processes and dies, and has functions such as the knowledge maintenance, the knowledge matching, the knowledge revise and so on. The general structure, key techniques and solution methods of this system were also analyzed.
