    Abstract
  • During the running process of high-speed railway train, the distribution regularity and cumulative process of random interference were analyzed.The status deviation map of running plan was used, and the change mechanism of running delay for high-speed railway train was described.During the running process of high-speed railway train, the distribution regularity and utilization process of redundancy time were analyzed.The status recovery map of running plan was used, and the process that redundancy time assimilated delay time was described.Based on the interacting process of running interference and utilization process of redundancy time, the generation mechanism of running conflict for high-speed railway train was studied, and the recurrent process of running status for high-speed railway train under the interaction of random interference and redundancy time was set up.The simulation system of running interference, redundancy time and conflict was developed by Yi language.While interference probabilities were 50% and 30% respectively and redundancy time proportions were 15% and 10% respectively, the generation mechanisms of running conflict for high-speed railway train under 4 conditions were simulated.Simulation result indicates that random interference can lead to the generation of running conflict, and redundancy time can absorb delay and reduce conflict numbers.The smaller random interference is, the fewer running conflict is.When interference probability reduces by 20%, the running conflict number reduces by 17.3%.The bigger delay is, the larger available redundancy time is.When the proportion of redundancy time increases by 5%, the coefficient of conflict absorption increases by 6.5%.The redundancy time plays more obvious role on absorbing running conflict when there are little interference probability and small total interference.
