Research and Design of 3D Vibration Test System Based on Vehicle Vibration Mode in Urban Rail Transit.

The vehicle vibration during operation in the urban rail transit aff ects the operation of the balise transmission system, resulting in the loss of beacons and the failure of the train positioning. Firstly, this paper analyzes the fundamentals of the balise fault caused by vehicle vibration theoretically. Then, a customized vibration test bench is designed and utilized to simulate vehicle vibration states during operation based on the structure of the balise transmission system and the status of vehicle movements. Finally, the simulations conducted using the vibration test system verify the reliability of the theory, enabling the provision of the corresponding preventive measures to reduce the loss of beacons and the failure of the train positioning.
