Abstract

This paper is devoted to the effect of accumulated damage to structural elements on the dynamic characteristics of a system, i.e., on natural frequencies and mode shapes, amplitudes, and forced-oscillation frequencies. This paper presents methods for the evaluation of the level of accumulated damage and approaches to the vibration diagnostics of technical systems by spectral criteria. A complex method for the analysis of the frequency and amplitude values of the dynamic response of the system by the wavelet analysis and data clustering using the method of fuzzy sets is also described.
