Strain Gauging – When?

During operations...

  • Measure real mechanical conditions during live service operations.
  • Even on moving / rotating machinery.
  • Monitoring for LONG PERIODS can capture UNEXPECTED events that do not occur every day
  • These events can often be the real cause of failure

Simultaneous monitoring...

  • Lines up the cause with the effect.
  • What actual stress results from that shock load?
  • Where was that rough road that caused those vibrations?
  • We can simultaneously monitor stress, strain, torque, load, pressure, displacement, vibration, location, velocity, acceleration and temperature.

Strain Gauging dovetails with FEA...

  • FEA can gives the stress picture over the whole structure.
  • But the LOADS are ESTIMATED.
  • Strain Gauging¬†gives stresses at certain points on the structure
  • So, the REAL LOADS are MEASURED
  • FEA + Straing Gauging = TOTAL PICTURE
