RESUMO

The analysis oí the dynamical behaviour oí structures is oí great economical and technological importance. The present work brings a contribution to this field, presenting time domam identification methods based on rea1ization theory. The methods are implemented for multivariable measurements through the use of the subspace approách. Numerical simulations are used to present the main characteristics oí the methods and to compare its performance with traditional techniques used in experimental moda! analysis. The proposed algorithms are also used in the moda! tests of two practicaI engineering structmes: an automotive exhaust system and a simplified aircraft wing mode!
