The Fault Diagnosis Method of Support Vector Machine Based on Kernel Fuzzy C-Means Membership

Article Preview

Abstract:

The rolling bearing is widely used in rail vehicles. The detection and diagnosis of the bearing is of great theoretical value and practical significance. The fault diagnosis method of support vector machine (SVM) based on kernel fuzzy C-means (KFCM) membership degrees can have very good results. Support vector machine based on statistical learning theory do well in terms of classification .This method clusters according to the sample membership degrees and puts data into nuclear space. It can highlight samples of differences in features. The training sample size has been greatly reduced, while training speed and the rate of correct classification is improved. The experiment results show that this method is feasible.
