There are different forms of abnormal vibration and abnormal noise of the EMU, involving many types of components, and many components cannot be judged through visual inspection, and some components cannot even be visually inspected. This article analyzes the characteristics of different types of vibration or abnormal sounds, and provides suggestions for troubleshooting and treating measures to guide subsequent similar failures.
