摘要
在研究我国直线段货物列车空车脱轨原因和预防措施中 ,通过大型综合脱轨试验和仿真计算 ,发现降低轮轨间摩擦系数能够明显改善空车的运行状态 ,大大提高其脱轨安全性 。
Through field test and computer simulation research, the authors have found that by reducing surface friction coefficient of rail/wheel could improve running status of freight vehicles distinctly and increase its running safety. This research result is very helpful to solve the problem of frequent derailment of empty vehicles running on straight track especially on track of just now replaced rail.
