基于仿真的铁路旅客列车提速潜力分析

Simulation-Based Analysis of Higher Speed Potential for Passenger Trains

介绍了我国铁路近年来在提高旅客列车运行速度中的措施 ,提出了旅客列车运行过程中采用目标速度策略对其进行控制的思路及算法 .通过对该策略的详细分析 ,从列车牵引计算的角度出发 ,利用作者开发的计算机仿真系统 ,对京广线旅客列车再提速的可行性进行了具体研究 。

This paper describes the historical actions of Chinese railways in increasing train speed. A target_based speed control policy, as well as its algorithm and implementation, has been advanced for train movement. Through detailed analysis to the requirement related to the policy, the paper has made a special case studies on the feasibility to realize higher speed of passenger trains with the simulator developed by the authors on Jing_Guang Railway. The results display that there is still a certain space on some sections to achieve higher speed under the current track and train environment.
