摘　　要：为了将薄壁管数控弯曲中积累的宝贵数据、经验知识进行充分共享和重用,文章采用面向对象的C#语言,基于Visual Studio．NET前台开发环境,SQL Server 2000后台数据库,研究开发了薄壁弯管数据库管理系统TUBE。TUBE中存储了大量经模拟和实验优化过的薄壁弯管工艺参数及成形结果;该系统中实现了对这些参数的查询、添加、修改、删除等基本功能,特别还能针对查询不到的记录,可以根据成形极限判断准则,结合已有成形参数及缺陷知识进行管子的预成形设计,再将预成形结果扩充到TUBE中,为实践提供快速、有效的指导。To share and reuse valuable data and experiential knowledge adequately, employing with object-oriented programming language C#, based on Visual Studio. NET developing environment and SQL Server 2000 database, thin-walled tube NC bending database management system TUBE was studied and developed in this paper. A great number of processing parameters and forming results optimized by simulation and experiment are stored in TUBE; the operations such as query, addition, modification and deletion were realized in TUBE. Especially for the record which couldn＇t be found in TUBE, the pre-forming design will be accomplished according to the forming limit and the existed or deduced defects knowledge in TUBE. The results obtained from pre-forming operation could be extended to TUBE and give a quick and effective guide to practice.
