为了解决目前航空钣金研制过程中存在的材料基础性能数据与成形工艺知识不足并无统一管理体系的问题,通过进行常用金属板料成形性能实验获取数据,总结了钣金6种成形工艺的知识内容,将信息录入通过Visual Studio和Oracla平台开发的航空钣金材料性能参数与工艺知识库系统,包括材料性能数据库、钣金成形工艺知识库和管理系统。该数据库可为钣金成形有限元模拟分析提供材料数据,并辅助工程师进行工艺性审查、工艺设计、工装设计和缺陷诊断,支撑钣金零件的整个数字化生产过程,缩短飞机研制周期,节约成本。
In order to solve the problem that there is no unified management system for the existing data of sheet metal performance and the lack of knowledge of the forming process during the current development of aviation sheet metal, the common sheet metal forming performance experiment is used to obtain the data and the knowledge of the 6 forming processes is summarized Content to enter information into aircraft sheet metal material performance parameters and process knowledge base systems developed through Visual Studio and Oracla platforms including material performance databases, sheet metal forming process knowledge bases and management systems. The database can provide material data for finite element simulation analysis of sheet metal forming, and assist engineers in the process of censorship, process design, tooling design and defect diagnosis, support the entire digital production process of sheet metal parts, shorten the aircraft development cycle and save costs.
