摘要
首先指出了国内外脱轨研究中存在的主要问题。提出列车脱轨能量随机分析方法。运用列车 -轨道时变系统空间振动分析理论及此种能量随机分析方法 ,对直线货物列车脱轨过程进行了计算 ,计算结果与实际线路工况下货物列车脱轨试验结果吻合。
The main existing problems in studying derailment at home and abroad are first pointed out in this paper, and then the energy random analysis method of train derailment is presented. Wheel derailment courses were simulated for a full scale freight train on tangent track from the point of view of spatial vibration analysis theory of train track time varying system and the energy random analysis method. The simulation results presented in this paper have good correlation with the test results of derailment of freight train on tangent track.
