An Approach of a Knowledge-based Process to Integrate Real Geometry Models in Product Simulations

Abstract

Simulation driven product development is state of the art to insure that the desired characteristics in use behave as requested without performing a time-consuming testing using expensive prototypes. To achieve the aim of realistic and confidential results within this product simulations, a tremendous afford (i.e. when taking different non-linearities into account, like material behavior, contact situations, large deflections etc.) is necessary. Conflicting to this, the ideal CAD-model is always used for the analysis, despite knowing the effect, that every manufactured component shows differences to its ideal geometry. Within this paper an approach of a knowledge-based process to integrate real geometry data into product simulations is given. Furthermore, different methods for preparation of the simulation models are represented.
