MODAL PARAMETERS EXTRACTION USING WAVELETS
 
Resumo :
ABSTRACT. THIS WORK PROPOSES THE USE OF WAVELETS IN MODAL PARAMETERS IDENTIFICATION OF VIBRATORY SYSTEMS. THE DEVELOPED METODOLOGY USES OPTIMIZATION TECHNIQUES AS A ISMATCHING PURSUITLN ALGORITHM MODIFICATION. SIGNALS OBTAINED FROM SIMULATION OF A VIBRATORY SYSTEM WITH ARTIFICIALLY ADDED NOISE AND FROM EXPERIMENTAL TESTS ARE USED TO EVALUATE THE METHOD ROBUSTNESS, ACCURACY AND RELIABILITY. THE METHOD PERFORMANCE IS COMPARED TO THE RUZZENE™S METHOD. KEY WORDS: MODAL ANALYSIS, WAVELETS, OPTIMIZATION.
