Study of Fault Diagnosis of Rolling Bearing Based on Experiment

The methods of fault diagnosis for rolling bearing are various which applied in different occasions.The power spectrum analysis technique and cepstrum analysis technique have been adopted separately to analysis the vibrating signal of the three typical faults of rolling bearing based on experiments.The results indicated that cepstrum analysis technique is more practical than power spectrum analysis technique in the fault diagnosis of rolling bearing.Also,comparisons have been made among noises detected during the running of the three fault bearings,which gives some reference to the fault diagnosis of rolling bearing.
