摘要
在保证运输安全的前提下,优化重载列车的运行时间控制,减少实际运行时间与计划时间的偏差,可以提高重载列车的运行效率。针对这一情况,提出基于运行时分控制的重载列车推荐曲线计算,使得重载列车的站间运行时间与合理的计划时间偏差小于5%。在建立重载列车力学模型的前提下,通过折半迭代法周期计算重载列车运行的推荐曲线,控制站间的运行时分,满足运行时间在合理的计划时间的偏差范围之内。仿真结果表明,采用运行时分控制算法控制的运行时间,与合理的计划时间的误差小于5%。
On the condition of ensuring transportation safety,the efficiency of heavy duty trains can be improved by optimizing the run-time control that reduces the deviation of the actual running time of the scheduled time. In view of this situation,a method of calculating recommendation curve of heavy duty trains based on run-time control algorithm is proposed,which can make the deviation between the running times of stations and a reasonable planning time less than 5%. Under the premise of the establishment of overloaded trains＇ mechanics model,the recommended curve of heavy duty trains is periodically calculated by binary iterative methods to control run-time and meet the running time in the range of reasonable planning time deviation. The simulation results show that the error of the running time that the algorithm controlled and the reasonable planning time is less than 5%.
