RLV-5500 Rotational Vibrometer - Applications

Fields of Application

Polytec’s rotational vibrometers measure torsional or angular vibrations, without contact, on arbitrarily shaped structures including engine crankshafts, vehicle axles, marine driveshafts, electrical generator shafts and rotating parts in lithographic machines, printers & photocopiers. Automotive engineers use the rotational vibrometer to develop torsional vibration dampers that reduce engine noise and increase product durability. Faults in gearboxes, compressors and generators cause torsional vibrations at certain system specific frequencies. Measurements are made to:

  • Reduce noise and vibration
  • Study rotational fatigue
  • Improve the precision and quality of tool-making machines
  • Monitor and trouble shoot power plant and production machinery
  • Speed up adjustment of torsional vibration dampers in vehicle drive shafts
  • Study run-up and run-down of machines (order tracking and Campbell plots)
