摘要
本文扼要分析了以有限元方法为基础的结构分析软件及其辅助系统─—智能化前端系统和模型化系统；然后结合黑板结构和真值维护系统，建立了一个综合模型化、数值求解和对数值结果的解释评价于一体的、基于知识的新型结构分析系统的概念模型；最后，基于有限元软件环境──ＳＥＦＥＭ，针对一类简单的结构系统，用语言实现了一个上述模型的简化系统──ＫＢｓＡＰ。
In this paper,structural analysis software based on FEM and its intelligent consultantsystem(Front-End System and Modeling System )are presented.A new conceptual model ofknowledge based structural analysis system,which integrates modeling,numerical solvingand result interpreting and evaluating.is established using blackboard structure and truthmaintenance system. As an example of this model,a simple system KBSAP using Clan-guage based on the Software Environment of Finite Element Methods(SEFEM)was imple-mented.
