Vibrodiagnostic system

Thesis discusses bearings failure detection that is manifesting with increased levels of vibration and acoustic emission. The first part of my work gives introduction to common disorders arising on bearings during operation and negative effects on the bearing condition. Further the thesis makes the reader familiar with the terms of vibration and acoustic emission. The work includes a description of available methods for signal evaluation of vibration and acoustic emissions in order to diagnose the state of the bearings in the domains of time and frequency. In the practical part is explained the vibrodiagnostic concept with focus on bearing endurance test. Part of this practical test is a balance sheet for hardware with marginal parametres and a software description. The work is complemented with sorted database of processed topics from the magazine Orbit Bentley Nevada
