Comparison of methods for identification of rolling bearing failures
Kokeš, Miroslav ; Hnidka,, Jakub (referee) ; Klusáček, Stanislav (advisor)
The aim of this master thesis is the comparison of selected methods and parameters for roller bearings diagnostics. Selected statistical parameters are kurtosis, crest factor, and parameter K(t). The other selected methods are envelope analysis, cepstral analysis, and ACEP method. These methods are implemented in LabVIEW software and compared based on noise resistance, computation speed, and overall capability of identifying roller bearing faults.

Fault Diagnosis of electrical machines using vibrations
Čech, Roman ; Hájek, Vítězslav (referee) ; Janda, Marcel (advisor)
The task of this thesis is to introduce the problems of vibrafon sources in asynchronous motor and their effects and risks to the engine. We will classify the sources of vibration, we will focus for the defects of bearings and for dynamic and static eccentricity. The thesis includes vibration measurement for asynchronous motor, analysis and evaluation of bearings defects and eccentricities.
