Short summary
In this paper, a new rotor rub-impact fault diagnosis method is proposed. The more sensitive fault features associated with the dynamics information are achieved based on the dynamic convolutional neural network. The experiment shows that the proposed method can obtain better diagnosis performance compared with traditional methods and that it has achieved the highest diagnosis accuracy of 98.5 % without noise and 98 % with noise.
