摘要
提出了一种含裂纹构件疲劳寿命模糊评估的方法 ;并以这个评估方法为基础 ,设计了一个结构疲劳寿命评估的专家系统。结果表明本系统采用知识的因素表示方法来表示知识和经验 ,适合处理模糊性知识 ;有对专家直接进行咨询的知识获取子系统 ,因而有较强的自动知识获取能力 ;推理模型采用特征统计推理法 ,结构可靠性程度高 ;具有启发式和人机交互式搜索策略 。
A fuzzy estimation method is proposed for structural elements bearing cracks. Basing upon this fuzzy estimation method, a fuzzy estimation expert system is designed for structural fatigue life. The result shows that this system suits to handle fuzzy knowledge, having subsystem to be consultated by experts owing to the fact that the system applies factors on knowledge to rpresent both the knowledge and the experience concerned. Therefore this system has much stronger ability to gain knowledge automatically. Its reasonal model adopts a statistical rersoning mathod. So this system is of high reliability, having a man machine searching tactics mutually, available for enlightening mode, and flexible in use.
