| Abstract: | Based on CAD, automatic mesh generation and AI reasoning techniques, the problem solving framework for finite element modeling (FEM) of aeronautical thin wall structures is introduced. The modeling process is characterized by the consecutive evolution of four models under four stages, and the content of each stage is given. The integrated knowledge representation scheme applicable to the above four stages of modeling is proposed. The blackboard architecture is adopted for managing task planning and control, domain knowledge reasoning and algorithm execution. It is believed that such framework is effective for constructing the practical FEM expert system of complex thin wall structures. |
