摘要: 介绍了运用面向对象原理与人工智能逻辑推理技术相结合的方法来构造航空结构有限元建模专家系统(OOFEMES).着重论述了系统的结构、功能设计与实现策略,包括领域知识的获取、分类、表达与组织,以及知识的推理与运算求解方式.给出了针对飞机结构不规则性(如开口、断接等情况)进行模型局部修正的任务处理流程,并通过应用实例,说明该系统应用的有效性.

Abstract: An Object Oriented Finite Element Modeling Expert System (OOFEMES), developed by combining the principle of object oriented programming and logical based reasoning is presented. The design and implementation of system function and structure are emphasized, which include the classification, organization and representation of domain knowledge, as well as the associated reasoning and computation techniques. A model correction diagram, taking into consideration the structural irregularity of aircraft structure is given. Through application example, it proves that the developed system is useful and effective for the analysis of aeronautical structures.
