Localization of errors in computational models using dynamic test data
Gerard J. Lallement, H. Andriambololona · Structural Dynamics · 2022
The accent is placed on the localization of the dominant modelling errors by a sub-space method. Other points also discussed concern the preparation of tests for a parametric identification: optimal selection of the pick-up positions with respect to: the reconstitution of the unobserved degrees of freedom; the orthogonality and the numerical conditioning of the Jacobian matrix.
