Abstract

We propose an adaptive method for the analysis of the dynamical changes in mechanical structures. Using measurement techniques and the flexible Gabor-wavelet transform, we perform an optimal denoising of slowly variable band-limited signals for an improved mechanical structure fault diagnostics.
