| 摘 要： | 根据对现有的压力容器、石油管道腐蚀失效案例和现有失效知识的分析与总结,提出了晶间腐蚀和氢致开裂两种模式的腐蚀失效特征。依据这些失效特征建立相应的两种腐蚀失效模式的失效判断规则,根据这些失效规则运用COM Wizard、数据库技术和可靠性技术建立有效的腐蚀失效模式诊断专家系统。该专家系统根据输入的腐蚀失效特征来识别案例的腐蚀失效模式并给出综合可信度作为诊断结果的评价参数。

| Abstract: | Corrosion failure features of intergranular attack and hydrogen brittlencss were generalized through analysis and sum-up on corrosion failure cases of pressure vessels and pipelines and the existing failure information. COM Wizard,data base technique,and reliability engineering were applied to construct an effective corrosion failure diagnosis expert system.Corrosion failure modes of real cases were analyzed in the expert system through the corrosion failure features input and the results were listed by gen... |
