The failure modes of the rolling bearing are analyzed, and the pulsation frequency of the bearing caused by the rolling bearing failure is estimated. By monitoring the vibration of rolling bearing, based on the vibration response power spectrum, the characteristic information of bearing vibration is found out, the reason of the failure of rolling bearing is analyzed, and the countermeasure to ensure the normal running of the bearing is put forward.
