Brake Fault Diagnosis through Machine Learning Approaches–A Review

引用

Structural Durability & Health Monitoring 2017年第1期11卷 41-61页

作者： t.M.alamelu manghai R.Jegadeeshwaran V.Sugumaran School of Mechanical and Building Sciences VIT University Chennai CampusChennaiTamil NaduIndia-600127

Diagnosis is the recognition of the nature and cause of a certain *** is generally used to determine cause and effect of a problem. Machine fault diagnosis isa field of finding faults arising in machines. to identify the most probable faults leadingto failure, many methods are used for data collection, including vibration monitoring,thermal imaging, oil particle analysis, etc. then these data are processed using methodslike spectral analysis, wavelet analysis, wavelet transform, short-term Fourier transform,high-resolution spectral analysis, waveform analysis, etc. the results of this analysis areused in a root cause failure analysis in order to determine the original cause of the *** paper presents a brief review about one such application known as machine learningfor the brake fault diagnosis problems.
