Bearing fault diagnosis base on multi-scale 2D-CNN model

Bearings play an important role as the connection between the motor and the gear. At present, the data collected by most motor bearing datasets are vibration signals in the one-dimensional time domain, and then one-dimensional convolution or other methods are used to analyze the signals. In this work, a fault diagnosis method based on continuous wavelet transform scalogram (CWTS) and multi-scale c...
