摘要
Abstract
The complex and changeable environment in the process of bearing operation may lead to inconsistent distribution of training data and test data,and decrease the diagnosis performance of the model.Thus a bearing fault diagnosis model based on the Shuffle-CANet is proposed,and realizes bearing cross-domain fault diagnosis by improving the ShuffleNet V2 and introducing asymmetric convolution.A domain loss function is added to the model based on the idea of domain adaptation in transfer learning so that the common features of the source domain and the target domain can be extracted occasionally and the cross-domain fault diagnosis can be realized.Compared with the traditional deep learning model,this model is friendlier to mobile and embedded devices.The Shuffle-CANet is validated by different transfer tasks on two different datasets.The results show that when the source domain and the target domain are derived from the same dataset,the fault diagnostic accuracy of the model can be more than 99%.When the target domain and the source domain are derived from different datasets,the fault diagnostic accuracy of the model can be more than 95%.关键词
