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.
