Research on Application of Cepstrum Analysis in Fault Diagnosis of Rolling Bearings
The use of cepstrum analysis has the"overview"ability for edge frequency components,which can easily extract and analyze the characteristics of periodic signals that are difficult to recognize by the naked eye on the original spectrum.The application of cepstrum analysis in rolling bearing fault diagnosis is discussed.By analyzing the experimental signals of two different sets of rolling bearing inner ring faults,the results show that in order to use cepstrum analysis for effective fault diagnosis of rolling bearings,it is necessary to reduce the impact of lower frequency vibrations in background noise on the collected signals during signal acquisition or signal processing.
