摘　　要：本文从CR400BF动车组经由车体平稳性监测功能发现的故障案例出发,通过对CR400BF动车组车体平稳性监测及报警逻辑进行研究,确定了导致车体平稳性指标超限的主要因素为线路或走行部技术状态不良,提出可通过对关键数据进行统计分析来确定平稳性指标超限原因,并根据分析结果有针对性地采取打磨线路、轮对踏面修型或更换技术状态不良配件等措施恢复车体平稳性。此外,本文通过总结分析,提出建立轮对踏面状态、走行部配件性能等数据模型的建议,探索轮对踏面恶化、走行部配件失效规律,从而推动动车组走行部维修模式从计划预防修向数字化精准预防修转变。Based on the fault cases found by CR400BF multiple unit s car body stability monitoring function,this paper studies the car body stability monitoring and alarm logic of CR400BF multiple units,and determines that the main factor causing the car body stability index to exceed the limit is the poor technical state of the line or running gear.It is suggested that the key data can be statistically analyzed to determine the reasons for the overrun of the car body stability index,and according to the analysis results,targeted measures such as polishing the line,repairing the wheel tread,or replacing the parts with the poor technical state can be taken to restore the car body stability.In addition,through summary and analysis,this paper puts forward suggestions on establishing data models of wheelset tread state and running gear parts performance,and explores the law of wheelset tread deterioration and running gear parts failure,thus promoting the change of multiple units running gear maintenance mode from planned preventive maintenance to digital precise preventive maintenance.
