Safety Assessment Expert System About Pressure Vessels Of Containing Flaw

Along with the rapid development of modern industry, the pressure vessels develop to the large-scale, complex, high parameter and the strict operating mode direction. The security of the pressure vessels arouses people's interest, and the safety assessment of the pressure vessels becomes more and more important. The pressure vessel once burst can create the huge economy loses even the significant disaster accident. Therefore, it is very important to carry on fracture assessment of pressure vessels in case of finding flaws. In order to offer convenience of pressure vessel management and maintenance and avoid some unnecessary repairs and discards, a"Safety Assessment Expert System"was establishedIn this article, the concept, development course, application prospect and the development and design of the expert system are introduced. The expert system uses the Windows2000 operating system as development platform, Visual Basic 6.0 as the main development language, and object-oriented programming thought is the basic method. The material parameter database and the classified stress database are established through database development language Access. The users can conveniently inquiry the dates through simple operation."Guide on methods for assessing the acceptability of flaws in metallic structures", BS7910, is the main engineering standard in safety assessment field. This article introduced the main content and method of BS7910, and the expert system is also based on BS7910.The appearance of the expert system is beautiful and friendly; the assessment process is simple and easy; the expansion performance is very good. Using the expert system may gain the satisfactory explanation of the question in very short-time.
