Weak Fault Feature Extraction of Rolling Bearings Based on an Improved Kurtogram
Kurtograms have been verified to be an efficient tool in bearing fault detection and diagnosis because of their superiority in extracting transient features. However, the short-time Fourier Transform is insufficient in time-frequency analysis and kurtosis is deficient in detecting cyclic transients. Those factors weaken the performance of the original kurtogram in extracting weak fault features...
متن کاملFast Automatic Background Extraction via Robust PCA
Recent years have seen an explosion of interest in applications of sparse signal recovery and low rank matrix completion, due in part to the compelling use of the nuclear norm as a convex proxy for matrix rank. In some cases, minimizing the nuclear norm is equivalent to minimizing the rank of a matrix, and can lead to exact recovery of the underlying rank structure, see [Faz02, RFP10] for backg...
متن کاملFault features extraction for bearing prognostics
This paper describes a newly developed fault feature extraction method for bearing prognostics. The effectiveness of the method is demonstrated with real bearing run-to-failure test data. Experimental results show that with the growth of the bearing defective area, the method is able to indicate clearer trends than the traditional condition indicators, such as RMS, the peak value, the amplitude...

15 صفحه اولUsing PCA with LVQ, RBF, MLP, SOM and Continuous Wavelet Transform for Fault Diagnosis of Gearboxes
A new method based on principal component analysis (PCA) and artificial neural networks (ANN) is proposed for fault diagnosis of gearboxes. Firstly the six different base wavelets are considered, in which three are from real valued and other three from complex valued. Two wavelet selection criteria Maximum Energy to Shannon Entropy ratio and Maximum Relative Wavelet Energy are used and compared...
