摘要：

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. (C) 2003 Published by Elsevier Science Ltd.
