Journal ArticleDOI
Fault diagnosis of ball bearings using machine learning methods
TL;DR: The results show that the machine learning algorithms can be used for automated diagnosis of bearing faults and it is observed that the severe (chaotic) vibrations occur under bearings with rough inner race surface and ball with corrosion pitting.
Journal ArticleDOI
Fault diagnosis of ball bearings using continuous wavelet transform
TL;DR: The test result showed that the SVM identified the fault categories of rolling element bearing more accurately for both Meyer wavelets and Complex Morlet wavelet and has a better diagnosis performance as compared to the ANN and SOM.
Journal ArticleDOI
Rolling element bearing fault diagnosis using wavelet transform
TL;DR: The fault classification results show that the support vector machine identified the fault categories of rolling element bearing more accurately and has a better diagnosis performance as compared to the learning vector quantization and self-organizing maps.
Journal ArticleDOI
Feature extraction and fault severity classification in ball bearings
TL;DR: Comparative study shows the potential application of proposed methodology with machine learning techniques for the development of real time system to diagnose fault and it’s severity in ball bearings.
Journal ArticleDOI
Stability analysis of a rotor bearing system due to surface waviness and number of balls
S. P. Harsha,Pavan Kumar Kankar +1 more
TL;DR: In this article, the stability analysis of a rigid rotor supported by ball bearings has been studied, where the contacts between balls and races are considered as nonlinear springs, whose stiffnesses are obtained by using Hertzian elastic contact deformation theory.
