Vibration monitoring and predictive maintenance

Plant maintenance is essential for safe operation and personal safety. Given its cost, however, it's a good idea to strike the right balance between systematic preventive and corrective maintenance.

Plant monitoring helps limit the need for preventive maintenance. In this context, vibration analysis is a tool for detecting and diagnosing plant malfunctions.

After describing the main vibratory manifestations of machine malfunctions, this article examines detection and monitoring strategies, and the diagnostic approach based on vibration analysis, which can be used to deduce maintenance policies and actions.
