朔黄铁路2万t列车操纵安全及对策

Safety Studies for and Measures of 20,000 t Train Operation on Shuohuang Railway

从1+1组合2万t列车纵向力、从控机车压钩力、小半径曲线受力及撞墙效应等方面分析2万t列车运行中存在的不安全因素,并结合朔黄铁路实际开行情况,从采用长波浪制动、长大下坡道列车缓解地点、再生力、减压量、关键站压后停车、侧线停车等方面制定具体措施,最后提出推广精细化操纵、树立安全红线意识等安全生产理念。

The paper first studies the potential risks in the operation of the 20,000 t combined trains （1＋1） from the perspectives of longitudinal force, coupler force of slave locomotive, force beating in passing curve sections of small radius and collision effect. Taking into account the operation status of Shuohuang railway, the paper suggests some practical means like long wave-type braking, the setting of release points along long downward slope, regenerative capacity, pressure decrement, brake delay at key stations and brake at sidings. On this basis, it proposes the general concept for both operation and workplace safety, for instance a more detailed approach in operation and be mindful of the red line for safety.
