重载列车制动对轨道纵向力影响的研究

Effect of Longitudinal Force on the Rail While Braking the Heavy Haul Train

本文采用有限元法,考虑了列车荷载下轨道阻力的作用,以及各种因素对纵向力的影响进行了分析和计算,并通过室内模型试验,验证了理论计算的正确性。

The effects of various factors (ballast resistance under train load, length of train, the position of locomotive in train composition, kind of rail, etc.) on the longitudinal force to the rail while braking the heavy haul train are analysed and calcuated with finiteel ement method. The result has been tested with track of similitude in the laboratory.
