โœฆ Synopsis

A plate model of the Garteur structure has been developed and updated. The cost function for the evaluation of the model's improvement consisted of residuals between calculated and measured natural frequencies and mode shapes. A brief description of the FE-model is followed by the presentation of the different modules used for the updating procedure, namely a substructure sensitivity analysis for parameter selection as well as an error localisation technique to detect modelling errors. The performance of the model is verified by different measured datasets, including data obtained by a modified structure.

In this paper an extension of the antiresonance-based model updating method that}by estimating antiresonances of unmeasured point FRFs}allows the use of previously identified modal data, is applied to the finite element model updating of the GARTEUR benchmark. The various steps of the process (model

A finite element model of the GARTEUR SM-AG19 test structure is updated. The philosophy applied in selecting the updating parameters is based on physical understanding, scrutiny of the mode shapes and sensitivity calculations. The 'corrected' model is shown not only to accurately reproduce test data

The classical inverse sensitivity approach was applied. In the presented application, the deviations between analytical and measured natural frequencies and mode shapes were minimised to update user selected stiffness, mass and geometric parameters. The selection of the updating parameters was based
