Case studies

Typical damage that can be detected with the vibration analysis system COMOS and evaluated in terms of depth of damage include:

  • blades: Static and dynamic unbalance , icing , misalignment of the rotor blades
  • bearing: Wear of main bearings (slow moving parts ) , the gearbox mounting (slow and fast moving parts) and generator bearings (fast moving parts )
  • Drive: Irregularity in the brake system, clutch, drive, oil pump
  • Gear: Wear of the teeth , incipient cracking and propagation
