Abstract
The paper deals with the updating of computational models for elasto-mechanical vibrating structures. The updating procedure is based on system identification techniques using an incorrect model on the one hand and measured data of the real system on the other. Some approaches with different types of measurement data are discussed. For practical realization the finite element program ADINA is combined with a nonlinear optimization algorithm and measured transfer functions are used for the correction of the design parameters. The application of the procedure is demonstrated by means of three examples.
