摘　　要：根据重载货物列车和高速旅客列车的发展需要，从列车运用工况、编组条件、司机操纵方法、线路条件、机车缓冲装置和制动装置等因素出发说明电力机车的纵向力以启动和车长阀制动工况为主。重载牵引用的电力机车应用新型的大容量缓冲装置；高速旅客列车牵引用的电力机车则可以采用２号或Ｇ１号缓冲装置。In view of the development need of heavy freight and high speed passenger trains,from the aspects of train running mode,marshaling conditions,drivers operation methods,railway line situation,locomotive buffers and brakes,it is demonstrated that the longitudinal effort displays itself mainly during start up and long valve braking.New type buffer with large capacity shall be adopted for heavy haul electric locomotives,while for high speed passenger electric locomotives,No.2/G1 buffer can be used.
