Techniques of vibration signal processing for enhancement of depth and reliability of bearings diagnostics

摘要

The results of experimental researches and mathematical processing of rolling bearings vibration signals were discussed. Manifestation of defect’s symptoms in spectra diagrams of vibroacceleration, vibrovelocity and vibrodisplacement was analyzed. Conclusion about possibility of using analyses of vibrovelocity and vibrodisplacement spectra diagrams for enhancement of depth and reliability of diagnostics.
