Abstract: At present, the working environment of most vehicle bearings is harsh, and the bearings are prone to various forms of failures. In this paper, a bearing fault diagnosis method based on vibration analysis is proposed. With the help of the LabVIEW software platform, a set of on-board bearing vibration monitoring system is designed by taking the transmission rolling bearing as an example. The system can keep the bearings in good working condition, and replace the bearings in time after the failure occurs to ensure the stability, safety and reliability of the vehicle operation, and conduct real-time condition monitoring and fault diagnosis for some vehicle bearings. It is of great significance to promote the development of intelligent diagnostic systems incorporating deep learning.
