Enhancing machine reliability through vibration analysis

All machines in operation generate vibrations. Because vibration is representative of the dynamic forces generated by moving parts, it occupies a privileged position among the parameters to be taken into consideration to ensure effective monitoring of machine operation. This is all the more the case as any change in a machine's vibration "signature" is often the first physical sign of an anomaly, and a potential cause, in the more or less long term, of a breakdown or deterioration detrimental to production, equipment longevity, finished product quality, or personnel safety.

These particularities make vibration analysis techniques, whether they are implemented to periodically monitor the evolution of a selected indicator (or set of indicators) until an alarm threshold is exceeded, or to establish a diagnosis ruling on the nature and severity of a failure and the urgency of intervention, one of the main tools for preventing breakdowns and studying how they occur.
