RESUMO

Works developed in this project are related to the Finite Elements Models updating techniques using experimental modal data. Firstly, the Numerical and Experimental Modal Analysis techniques are presented. Models updating methods are also presented with a particular interest in iterative methods. During the bibliographical study, algorithms of parametric identification and FE models updating were developed. The didactic example of a beam has been used to evaluate these algorithms. Finally, a methodology of FE models updating was elaborated in Matlab and applied to the FE model of Test Rig for Simulation Dynamic Behavior of hydrogenerators of the Laboratory of Vibrations and Dynamics of the Structures of UnB. The results obtained are presented and analyzed in order to show that the methodology developed is applicable in industry.
