In this paper, the determination is considered of the required experimental accuracy that must be attained when updating finite element models with use of measured vibration test data. A theoretical basis is developed for FRF-based updating techniques, as these use measured data directly. It is show
Model updating techniques are used to update a "nite element model of a structure so that an updated model predicts the dynamics of a structure more accurately. The application of such an updated model in dynamic design demands that it also predict the e!ects of structural modi"cations with a reason
