近年来,在列车的全面提速中,有为数不少的货运车辆在空载状态、运行速度达70 km/h左右时出现蛇行失稳现象,成为我国干线铁路提速危及行车安全的严重隐患。“车辆运行状态地面安全监测系统”在测试技术、传感器研制等方面取得较大突破,实现了多项检测功能的集成,即识别运行状态 In recent years, when the number of freight vehicles in a full speed-up of a train is in a no-load state and the running speed reaches about 70 km / h, the phenomenon of meandering instability occurs, which becomes a serious hidden danger of speeding up the traffic safety of the trunk railway in our country. “Vehicle running status ground safety monitoring system” has made great breakthroughs in testing technology and sensor development, and has realized the integration of multiple detection functions, that is, the operation status
