Design of Database Application System for Hull Structural Steel and Welding Materials
-
摘要: 为了解决结构钢及焊接材料数据的有效存储及高效利用问题，使用SQL Server作为后台数据仓库，VB作系统开发，ODBC数据源作为连接技术，设计开发了船体结构钢及焊接材料数据库应用系统。系统具有结构钢及焊接材料信息查询、标准及报告查询等四大功能模块，并以结构钢配套焊条为例，通过性能预测智慧框架和神经网络模型构建、神经网络矩阵模型转换为VB代码等工作，实现了其力学性能预测，对结构钢及焊接材料设计有一定的参考和实用价值。Abstract: In order to promote the storage validity and utilization efficiency, the database application system of hull structural steel and welding materials is designed and developed by using SQL Server as background database, VB as system development and ODBC data source as connection technology. The system has four functional modules:structural steel information query, welding material information query, standard query and report query. Structural steel welding rod has been taken as an example to test the practicability of the system. The mechanical performance prediction is realized by the construction of the intelligent framework for performance prediction and the neural network model, and the transformation of neural network matrix model into VB code. It has a certain reference and practical value for the design of structural steel and welding materials.
