高坡地段防止货物列车分离、断钩问题的理论探讨

Discussion of Prevention Freight Train from Coupler Broken on Gradient Section

利用列车牵引计算学的理论对高坡地段经常发生的列车分离、断钩的机理进行了探讨 ,并以石太线易发生货物列车分离、断钩事故的现状为例 ,分析了使用空气制动存在的弊端 ,以及使用电阻制动的优点 。

Using the theory of train traction calculation,the mechanism for train separation and coupler broken often occured on gradient section is discussed.Examples are cited from actual accidents of freight train separation and coupler broken on the shitai line for the analysis of the disadvantages of using air break and the advantages of using rheostatic brake.Key problems are identified for proper use of combined electro-pneumatic brake on gradient sections to realize smooth and stable operation of a freight train.
