Abstract:

Finite element method could be effectively used in computer-aided engineering. Unfortunately, it still rarely used in industry. One of the causes is high costs of such software, as well as lack of highly qualified specialist. In this paper, the possibility of developing of rule based system for aiding of FEM simulations designing. Prototype of inference engine working with knowledge base storing engineering knowledge is used. Tests are based on simple rod rolling process. Process of optimisation of technological parameters with both FEM computations and rule-based inference is shown in this article. Temperatures and shape of rod are chosen to be optimised. Abaqus 6.7 software is used for FEM, while newly developed modelling language is used in inference. It is based on terms similar to predicates in First Order Logic and variables. It is shown, that quite simple set of rules allows finding proper solution in relatively low number of simulations. Some additional constraints and requirements are also described.
