Validation and Improvement of Body Panels FE Models from 3D-Shape and Vibration Measurements by Optical Methods

In this paper, we propose a strategy for validation and improvement of structural finite elements (FE) models using vibration and 3D-shape optical measuring method. The main advantage of these methods is to provide a whole field information allowing to speed-up the measurements, combined with an high spatial resolution ensuring updating quality. This strategy is especially adapted to the improvement of light weight body panel structures. Several application examples are presented.
