Vibration Analysis


Vibration analysis is a process of looking for anomalies and monitoring change from the established vibration signature of a system. The vibration of any object in motion is characterized by variations of amplitude, intensity, and frequency. These can correlate to physical phenomena, making it possible to use vibration data to gain insights into the health of equipment.


Vibration analysis can be used to

  1. Find a developing problem that can be repaired to increase machine lifetime
  2. Establish acceptance testing criteria to ensure that installation/repairs are properly conducted
