SAMMANFATTNING
This work concerns different vibration analysis techniques for detection of
local defects on bearings. Beginning by discussing a signal model we have
developed several possible solutions to the problem, where wavelet
techniques have been an integral part. Without using historical data or
doing fine adjustments we have achieved an error rate of approximately 10%.
