空载货运列车脱轨检测系统的研制

根据朔黄铁路实际情况,提出一种适应朔黄铁路特殊线路条件并能准确检测车辆脱轨倾向的脱轨预警系统。分析了系统工作原理和结构,建立了测量轮轨间横向和垂向相对位移、作用力以及车轮加速度的方法,结合脱轨判据综合判断车辆脱轨倾向,最后分析了该系统的效益。

According to actual situation of the Shuohuang Railway,a derailment warning system is developed that can adapt to the special conditions of the Shuohuang railway and can detect the tendency of derailment accurately.The working princi- ple and structure of the system are analyzed.To judge derailment tendency combined with the derailment criterion,a method for measuring horizontal and vertical relative displacement between wheel and rail,the force and wheel acceleration was established.At last the effectiveness of the system is analyzed in this ~aper.
