Abstract

The current design analysis process used by many areas of industry lends itself ideally to the application of a knowledge based engineering (KBE) approach. Currently any geometry provided to an analyst by a computer aided design (CAD) system of a structure usually has to be simplified before the creation of a finite element (FE) mesh and subsequent structural analysis. This simplification and mesh creation process can be very time consuming. It is possible with the use of a KBE system to provide the rules and knowledge such that the geometry produced in the system can first be automatically simplified as required by an FE pre-processor and then meshed. The material properties and boundary conditions can also be applied at this stage if standard, and the elements grouped in such a manner to facilitate ease of manipulation by the analysis system. The work undertaken here shows the feasibility of this process for the design and analysis of a simple gear wheel. However, now that the feasibility of the approach is seen to be valid, it is believed that this process can be applied to much more complex structures such as an automotive body-in-white structure.
