Vibration Analysis of Rotating Machinery

Applied to accelerometer data (or audio recordings) of rotating machinery, Sunics reveal aspects of the data which are hardly accessible via the time-waveform or spectrum. These include:

  • localization of faults in time and phase
  • slowly occuring changes (low frequency components)
Example (simulated data): sunic (bottom right) clearly illustrates how a strong impact (blue curve) changes its phase (vertical axis) over time (horizontal axis). This is difficult to see in the time-waveform (top) and missing in the spectrum (bottom left).
Example (simulated data): sunic (bottom right) clearly illustrates how the phase location of a misalignment slowly changes.
