摘要
列车运行时的振动会影响应答器传输系统工作,导致信标丢失,无法实现列车定位.理论分析振动引起故障的内在原理;根据应答器传输系统构成以及列车运行时的状态,定制振动试验台来模拟列车运行时的振动情况;通过振动试验系统测试来验证理论的可靠性,从而有针对性的采取防范措施,减少信标丢失造故障.
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.
