Abstract

Rolling bearing fault diagnosis methods based on convolutional neural networks (CNNs) have demonstrated excellent capabilities in processing complex nonlinear signals. Among them, the one-dimensional convolutional neural network greatly accelerates the signal processing process by directly processing the one-dimensional time-series signal and simplifying the input of the model. However, the traditional 1D convolutional neural network has problems such as poor feature recognition. In this paper, we propose a model based on the fusion of the attention mechanism CBAM and the deep convolutional neural network with a wide kernel in the first layer (WDCNN), which emphasizes the key features and suppresses the irrelevant noises, and significantly improves the model's recognition ability for fault features. The improved method is compared with other diagnostic algorithms to verify its higher accuracy and more stable training process.
