摘　　要：磨万铁路是采用中国标准建设的时速160 km客货共线铁路,货物列车牵引质量3000 t,由2台HX_(D)3C型机车牵引。磨万铁路磨丁—万荣段最大坡度为24‰,在长大坡道区段,上坡道受机车牵引能力限制,下坡道采用空气制动调速时,列车运行速度均明显降低。研究货物列车运行速度受坡度的影响及长大坡道上的货车动力学响应,为磨万铁路货物列车操纵提供参考。Boten-Vientiane Railway is a 160 km/h mixed passenger and freight railway constructed under Chinese standards,with a tractive mass of freight trains up to 3000 t by two HX_(D)3C locomotives.The maximum slope in the Boten-Vang Vieng Section of Boten-Vientiane Railway is up to 24‰.In the section with long steep grades,the operating speed of an upgrade train is limited by the traction capacity of the locomotive,and that of a downgrade train,which is subject to speed regulation by air brake,decreases obviously.The impact of the grade on the operating speed of freight trains and the dynamic response of the freight trains in long steep grades are researched to provide a reference for the freight train operation of Boten-Vientiane Railway.
