Abstract: The vehicle vibration during operation in the urban rail transit affects 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.

Key words: balise transmission system, vibration test system, beacon, urban rail transit
