To achieve efficient bearing fault diagnosis
a novel method based on the IEC module (integrating InceptionV2
Efficient Channel Attention
and Convolutional Block Attention Module) and a Two-stream Convolutional Neural Network(TSCNN) is proposed. First
raw vibration signals are converted into one-dimensional data and two-dimensional time-frequency images using Fast Fourier Transform(FFT) and Continuous Wavelet Transform(CWT). Subsequently
an improved TSCNN fusion model is constructed
and the obtained wavelet time-frequency images and FFT spectra are used as inputs to extract the spatial features of the time-frequency images by using InceptionV2 and ECANet-CBAM improvement module
and the resulting dual-layer feature information is fused into the Softmax layer to accomplish fault classification. Finally
comparative analysis based on a standard rolling bearing fault data set demonstrates that the proposed IEC-TSCNN method achieves superior diagnostic accuracy.
