METHODS FOR VIBRATION DIAGNOSTICS OF THE INITIAL STAGES OF DAMAGE OF ROTATION SYSTEMS

摘要

We present the main ideas of methods for early diagnostics of mechanical rotation systems based on the theory and statistics of periodically nonstationary random processes regarded as a mathematical model of signals of vibrations. New diagnostic criteria for defects are proposed, and new possibilities that they open are shown. The application of the developed methods to the early diagnostics and detection of defects of bearing units at the Dobrotvir thermal power plant is described.
