The health status of the bearings, in addition to directly affecting the functionality of the entire equipment, is also the main cause of equipment failure; therefore, how accurate the assessment is The health of the bearing is very important. There are some problems in the traditional bearing fault diagnosis, including bearing fault diagnosis only at the same speed, in order to solve the appeal problem; therefore, this study will design a bearing fault diagnosis system for bearings with different speeds. The system uses a convolutional neural network. Based on this, a neural network model with different height and rotation speeds was constructed and a bearing fault diagnosis system with a span speed was built through a deep learning neural network. To demonstrate the credibility of the method, a case with credibility was used in this study. Western Reserve University Bearing Information Center, the data center site has provided a bearing vibration fault signal, and use the bearing signal provided by the site to verify the method proposed in this study, experiments have proved that this method is effective. In the article's experimental results, the study achieved simultaneous classification of bearing data with different high and low speeds, and the use of the network neural network model to successfully classify the speed data not involved in the modeling, and the correct rate of up to 99.66%.故障診斷卷積神經網路深度神經網路機器學習Fault DiagnosisConvolution Neural NetworkDeep Learning Neural NetworkMachine Learning
