Incipient fault diagnosis of rolling element bearing based on wavelet packet transform and energy operator
This paper mainly deals with the issue of incipient fault diagnosis for rolling element bearing. Firstly, an envelope demodulation technique based on wavelet packet transform and energy operator is applied to extract the fault feature of vibration signal. Secondly, the relative spectral entropy of envelope spectrum and the gravity frequency are combined to construct two-dimensional features vec...
متن کاملApplication of Wavelet Packet Transform (WPT) for Bearing Fault Diagnosis
The bearings are the most important mechanical elements of rotating machinery. They are employed to support and rotate the shafts in rotating machinery. On the other hand, any fault in bearing can lead to losses on the level of production and equipments as well as creation an unsafe working environment for human. For these reasons, Condition monitoring and fault diagnosis of these bearings has ...
متن کاملState Monitoring and Early Fault Diagnosis of Rolling Bearing based on Wavelet Energy Entropy and LS-SVM
Rolling bearing is one of the most widely used elements in rotary machines. In this paper, a novel method is proposed to extract early fault features and diagnosis the early fault accurately for rolling bearing. Wavelet Energy Entropy is introduced as a feature parameter for bearing state monitoring and least square support vector machine (LS-SVM) is used for early fault diagnosis. In order to ...
متن کاملRolling Bearing Fault Diagnosis Based on Wavelet Packet Decomposition and Multi-Scale Permutation Entropy
This paper presents a rolling bearing fault diagnosis approach by integrating wavelet packet decomposition (WPD) with multi-scale permutation entropy (MPE). The approach uses MPE values of the sub-frequency band signals to identify faults appearing in rolling bearings. Specifically, vibration signals measured from a rolling bearing test system with different defect conditions are decomposed int...
متن کاملFault Diagnosis of Diesel Based on Wavelet Transform and SVM
A fault diagnosis method based on wavelet transform and support vector machine is proposed for diesel engine. The continuous wavelet transform is used to analyze vibration signals of surface of diesel engines, and scale interval is chosen according to size of wavelet information entropy, then local energy on wavelet domain are extracted as the fault feature vector, which are eventually input in...
