A New Time-frequency Domain Feature Extraction Method for Rolling Bearing Fault Diagnosis

A New Time-frequency Domain Feature Extraction Method for Rolling Bearing Fault Diagnosis

For fault diagnosis of rolling bearings,a new feature extraction strategy based on short time Fourier transform（ STFT） and bag of wordss（ BOW） is proposed. Based on the generate mechanism of bearing fault,the different bearing vibration signals have relevant energy distribution. But in the factory,s...
