腐蚀损伤评价专家系统的研制及开发

RESEARCH AND DEVELOPMENT FOR CORROSIONDAMAGE CASE ANALYSIS AND EXPERT SYSTEM

采用C ++Builder集成开发环境和关系型数据库Paradox ,研制开发了基于Win32平台的腐蚀损伤评价专家系统 .系统包括了四个模块 ,腐蚀案例库模块、分析树模块、实验报告模块和网络资源模块 .腐蚀案例库用于存储大量的腐蚀数据 ,每个腐蚀案例是由 7个案例模块 (概述、环境、材料、部件、测试、腐蚀、失效 )构成 ,每个模块下又包括若干个子模块 ,总共 172个字段 ,收集了国内和欧洲工业装置维护中发生的 6 0 2个失效案例 ,实现了案例的增加、编辑、保存、删除、检索和打印 .分析树用于腐蚀现象的分析过程 ,包括 19种失效分析过程模板 (如开裂失效、机械失效、炼油厂管道、奥氏体不锈钢的氯离子应力腐蚀等 ) ,根据相应的决策树进行不同环境 /材料体系进行腐蚀失效分析 ,并提出失效和防护建议 .实验报告和网络资源是对系统有益的补充 ,分别用于保存实验报告结果和与腐蚀相关的书籍、杂志、中心、数据库等网址信息 .系统功能明确、可视化程度高、操作方便、容错能力强、易于移植 .

Corrosion is harmful to the useful lifetime of materials.In general,the phenomena of corrosion are complex models,and have a vast set of responsible factors for its appearance.Therefore,we develop corrosion damage case analyses and expert system with C++ builder and paradox in order to manage corrosion data and analyse corrosion procedures.Corrosion damage case analyses and expert system is composed of atlas of corrosion case history,failure analysis procedures,reports and links to internet.Atlas module can save lots of corrosion cases.The module,composed of general,environment,material,component,test,corrosion and failure,includes 172 fields,and collects 602 cases in China and Europe industry.Procedures module has a main goal of the corrosion case analysis through several procedures already defined.Those procedures have a decision-tree format with different status that allows to obtain a conclusion about the fail cause through its own navigation.Reports and links module can save report results and internet links of corrosion respectively,which are complements to the system.
