Abstract


In general, every component shows differences to its ideal geometry of the

designed CAD-model, i.e. due to deformations in the production process. Despite

knowing the effects of deformations, the product developer always uses the ideal,

non-deformed design model of the CAD-system for FE-simulations of a component.

It seems rather doubtful that further refinement of simulation methods (e.g. using

different non-linearities) makes sense, if the real manufactured geometry of the

component is not considered for in the simulation process. Therefore, this paper

describes an approach to use hybrid geometry models for simulations, which are

mostly built of the parametric CAD-model, but areas with large deviations are

substituted with surface reconstructed scan-inserts based on 3d surface scanned

data, reconstructed to NURBS-patches. This procedure allows a more precise

simulation as it considers deviations by minimizing the amount of data and the

time for model preparation.
