MONITORING AND DIAGNOSIS OF ROTATING MACHINES BY VIBRATORY ANALYSIS

Vibration monitoring can be an effective method of achieving results, and sometimes at lower costs. This last point, which represents the economic aspect of surveillance, is not negligible for an industrialist. The use of the vibrations involves a phase of analysis of the vibratory signal collected on the machine to be monitored.In our experimental study at the level of the URMA laboratory, we made several tests, namely, without and with defects in the bearings and with a bearing geometric defect at different rotational speeds.
