Correlation, error-localisation and updating of the second problem defined in GARTEUR AG11

A description is given of the second problem, a clamped-free truss structure, defined in the GARTEUR Action Group 11. The measured and calculated modal data of the structure are correlated, the locations of the errors are determined and finally the finite element model of the structure is updated. These analyses are performed with the B2000...

Methoden voor het verbeteren van dynamische modellen van constructies

A survey of computational methods to improve dynamic analytical models described in the literature is made. Both the matrix methods and the optimal correction method of the dynamic model using the measured modes are discussed.
