Abstract
This paper proposes a method for detecting the change of mechanical vibration modes by means of a blind system identification method based on statistic independence. If a fault breaks out in a machine under disturbance, the method makes it possible to find the change in system parameter without sensing the vibration source directly. Experiment with a flexible structure has been carried out to verify the effectiveness of the method.
