摘　　要：描述了大功率交流传动电力机车牵引重载货运列车在过分相后,由于车钩连接间隙、运行速度、运行线路情况等因素引起的机车与列车、列车之间的反复纵向冲动现象,分析了机车与列车、列车之间出现纵向冲动的原因及对车辆的钩缓装置、轮对等部件的影响,同时提出了相应的电力机车牵引控制优化策略,使机车与列车平缓加速,减小机车与列车纵向冲动。This paper first describes AC electric locomotive and heavy- duty freight train longitudinal impulse influence phenomenon after passing phase separation caused by some factors such as the coupling clearance, running speed, running lines et al.. Analysis the reason of the longitudinal impulse between the locomotive and trains and the influence of the coupler draft gears and wheels, and then put forward an electric locomotive traction control optimization strategy let the locomotive and trains accelerated smoothly and reduce the locomotive and train longitudinal impulse.
