摘要
探讨了列车牵引力学条件下的铁路列车节能操纵问题,开发了一套可用于不同运行条件下的列车节能操纵仿真软件。系统重点探讨了定时约束条件下的列车节能操纵的模型及其启发式解法,详细分析了基于目标速度的列车控制策略以及专家控制原则。根据实际运行环境对内燃机车进行了实例分析,优化操纵方案与实际操纵相比,平均节能率在8.0%左右。系统计算速度快,人工干预方便,可以满足现场的实际需求。
This paper explores the simulation problem on train energy-efficient operation with fixed running time. A simulation system has been developed suitable for different running conditions and train parameters. As an emphasis, the paper discusses the optimized model and the heuristic algorithm for locomotive to work under the practical operating environment. The paper also analyzes the control strategies base on the target speed and describes the knowledge expression of train expert control. An application of the methods on the energy-efficient operation for long-haul freight trains in an uneven railroad has been presented. The average energy-efficient ratio is about 8.0%. With the aids of simulator, the algorithm can provide a fast simulation results and expediently human interference for the practice.
