高速铁路联调联试单列综合检测列车逐级提速计划制订方法研究

A Study on the Method of Formulation of Gradual Speed Increase Plan for the Integration Test and Commissioning of High-Speed Railways with Single Comprehensive Inspection Train

高速铁路联调联试逐级提速计划的合理制订对按时、高效地完成项目至关重要。基于离散事件理论,考虑单列综合检测列车逐级提速测试准则,结合每个单程测试及相互间的逻辑关系,建立基于离散事件的逐级提速计划制订模型,并设计相应的动态演化算法,求解计划用时总天数和停轮天数。通过长昆客运专线富源北至昆明南段单列综合检测列车联调联试逐级提速实例分析,验证了模型和算法的有效性,并且进一步分析了模型中不同参数变化对提速计划的影响。研究结果可以为联调联试逐级提速计划制订提供理论依据。

The rational formulation of the speed increase plan for the integration testing and commissioning of the high speed railway is very important for completing the project on time and efficiently.Based on discrete event theory,considering the test criteria of gradual speed increase of single comprehensive inspection train,combined with each one-way test and the logical relationship between them,this paper establishes a formulation model of the speed increase plan based on discrete events,and designs the corresponding dynamic evolution algorithm to solve the total number of days and the number of stopping rounds.Through the analysis of the case study of the testing and commissioning of Fuyuan North to Kunming South section of the Changsha-Kunming passenger dedicated line,the effectiveness of the model and algorithm is verified,and the influence of the change of different parameters in the model on the speed increase plan is further analyzed.The research results provide a theoretical basis for the formulation of the gradual speed increase plan.
