高速铁路列车运行图稳定性研究

Research on the Stability of High-speed Railway Train Diagram

在分析列车运行图稳定性含义的基础上,提出基于异质度的列车运行图稳定性研究。首先分析了异质度的含义及异质度与列车运行速度的关系,接着阐述异质度与列车运行图之间的关系,提出以列车运行图异质度作为关键指标,定量研究列车运行图的稳定性。选取京沪高铁、武广高铁、郑西高铁以及京津城际、沪宁城际实际列车运行图进行实例验证,探讨列车运行图异质度差异的主要原因,为列车运行图稳定性评价提供了思路,以求促进列车运行图的深入研究,进一步提高高速铁路列车运行图编制质量。

Based on the analysis of the stability of train operation diagram, the stability of train operation diagram based on heterogeneity is proposed. Firstly, the meaning of heterogeneity is analyzed, and the relationship between heterogeneity and train speed is analyzed. Then, the relationship between heterogeneity and train diagram is expounded, and the stability of train operation diagram is quantitatively studied. This article analyzes the actual train operation diagram of Beijing-Shanghai high-speed railway, Wuhan-Guangzhou high-speed railway, Zhengzhou-Xi'an high-speed railway, Beijing-Tianjin intercity railway and Shanghai-Nanjing intercity railway, then analyzes the main reasons for the difference of heterogeneity of train operation, providing a reference for the stability evaluation of train operation diagram, and further studies the train operation diagram to further improve the quality of high-speed railway train diagram.
