Main Article Content
Abstract
National Technical University of Ukraine "Kiev Polytechnic Institute",
The article investigates the possibilities of application of autoregressive methods PSD estimates based on simulation and design of virtual spectrum analyzer for vibrodiagnostics tasks, with subsequent applications to address problems of identification of equipment problems. Simulation model has developed in the form of virtual spectrum analyzer to the basic method of parametric estimation of power spectral density by Berg.
A comparative analysis of the results of the parametric spectral analysis with the results of the classical fast Fourier transform algorithm based on real data obtained in the study of phase laser vibration sensors. The experimental studies have been carried out using the developed virtual devices for estimate PSD of real vibration signals.
