摘　　要：高速动车组在两个停车车站之间运行,如按照时刻表规定的运行时间计算的区间平均速度为目标速度,则必然晚点。如按照轨道设计限速运行,则必然早于时刻表到站。在这两个速度之间,存在一个“理想目标速度”能确保高速动车组准时到站。文中通过建立并分析高速动车组的能耗模型,认为高速动车组的能耗方程是速度的3次方。因此,通过迭代算法找到的“理想目标速度”,就能同时满足高速动车组准点到站和能耗最低两大要求。通过仿真对比,证明该节能算法完全能满足这两大要求。High speed EMU operates between two parking stations.If the interval average speed calculated according to the running time specified in the timetable is the target speed,it must be delayed.If the train operates according to the designed speed limit of the track,it must arrive at the station earlier than the timetable.Between these two speeds,there is an"ideal target speed",which can ensure the arrival of high-speed EMU on time.By establishing and analyzing the energy consumption model of high-speed EMU,this paper considers that the energy consumption equation of high-speed EMU is the third power of speed.Therefore,the"ideal target speed"found by iterative algorithm can meet the two requirements of punctual arrival and minimum energy consumption of high-speed EMU at the same time.Through simulation comparison,it is proved that the energy-saving algorithm can fully meet these two requirements.
