Abstract

Journal of Vibration and Control, Ahead of Print.
In this work, an improved attention mechanism rolling element bearing (REB) fault diagnosis method based on a convolutional neural network (CNN) and a Bi-directional long-short term memory (BiLSTM) is proposed. The original REB fault signals of 10 ...
