摘要
朔黄铁路亟需通过提高列车轴重、增加编组长度来增强铁路运输能力,但神池南—西柏坡段多为10‰左右的长大下坡,提高轴重、增加编组后如何保证列车在该路段的行车安全是倍受人们关注的难题。为此,本文针对30t轴重2.3万t重载列车在长大下坡段如何施加空气制动进行研究,提出相应的空气制动运用方法;同时,对该路段的节能策略进行研究,提出了相应的节能理论,并通过仿真分析验证其有效性。仿真结果表明:提出的空气制动运用方法能够有效保证30t轴重2.3万t重载列车在长大下坡段的安全运行,并能够提高发电量,节约能耗。
Currently,Shenchi-Huanghua railway requires enhancement of the capacity of transport by improving the train axle load and length.However,the slope gradient is up to 10‰in Shenchi South-Xibaipo section,the operation safety of trains in the section after the increase of the axle load and train length has received widespread attention.To solve the problem,this paper studied the application of of air brake to the 30 taxle load and 23 000 theavy haul train running on the long heavy down grade section and proposed an air brake application method.Meanwhile,an energy-saving strategy for this section was studied and the corresponding energy saving theory was put forward and the validity of the proposed technology and strategy was tested by simulation in the end.The results show that the air brake application method can effectively ensure the safety of 30 t axle load and 23 000 theavy haul train running in the long heavy down grade section and the energy-saving strategy can increase power generation and save energy.
