23 The Influence of Geometrical Correlation in Modal Validation Using Automated 3D Metrology 243 Fig. 23.4 The comparison of the scan and the CAD data using the GOM Inspect software Fig. 23.5 The comparison of CAD deviations in geometry structure is a decisive factor in changing its modal parameters. If the geometrical correlation is neglected or assumed to be good, the inaccuracies in the first step will make the entire correlation and validation inaccurate. The R&D field of structural analysis in every industry, on the whole, has a greater responsibility of the structure’s quality assurance. The development of a validated dynamic model of a structure is fast-becoming a very important tool, for sensitivity analysis of various parameters, for differentiating between good and damaged structures etc. Geometrical correlation is a very influential factor and needs to be considered in this process of modal validation.
