VIBRATION ANALYSIS

Vibration is the ratio between the Force and Stiffness. In simple terms, Vibration is a ”To and Fro motion of a body from its position of equilibrium”

Five Characteristics of Vibration

  • Amplitude
  • Frequency
  • Phase
  • Shape
  • Position

We, Vibsys Technical Services, are equipped with most advanced tools to perform detailed Vibration Monitoring & Diagnostic studies in field. Our Lead Analyst is certified as Vibration Analyst – ISO 18436 Category IV.

Following are some of the plots used in Vibration analysis study.

  • Time Waveform
  • FFT spectrum
  • Envelope / PeakVue Spectrum analysis
  • Orbit Plot
  • Shaft Centreline Plot
  • Polar / Bode Plot
  • Waterfall / Cascade plot

Vibration Analysis is by far the most widely used condition monitoring techniques due to the fact that It will be useful to detect the majority of the Mechanical and Electrical failures. Here are the list of Rotating machinery anomalies that could be detected using Vibration Analysis.

  • Unbalance
  • Misalignment
  • Mechanical looseness
  • Bearing failures
  • Gearbox failures
  • Aerodynamic issues
  • Cavitation, Re-circulation, Flow turbulence, etc
  • Resonance, Critical speeds and Natural frequencies
  • Electrical motor faults
  • Cracked and Bent shafts
