Fault Classification of Water Hydraulic System by Vibration Analysis with Support Vector Machine

CODEN: JTEVAB

Abstract

This paper presents a new neural network approach to the fault diagnosis of a water hydraulic system based on the wavelet analysis of a vibration signal. A novel feature of this approach is that the vibration signals acquired from the water hydraulic motor are employed for analysis. Wavelet transform (WT) is first applied as a feature extraction technique to analyze the time-domain vibration signal. The performance of support vector machine (svm) is then investigated and compared with the conventional neural network. The results confirm the applicability of the proposed method for the fault detection in a modern water hydraulic system.
