基于自动恒速的客运专线列车牵引计算模型与算法研究

客运专线列车的控制模式与普通铁路的相比较存在较大差异,这使得普通铁路列车牵引计算模型不适于客运专线。论文在对客运专线、普通铁路及地铁差异分析的基础上,构造了自动恒速的列车牵引计算的模型与算法。将列车运行过程分为起动和牵引加速过程、恒速牵引过程、调速制动过程及进站制动过程四部分,对各部分分别建立了计算流程。最后对照非恒速牵引计算模型,测试了所造模型和算法的有效性。

Passenger Dedicated Train Traction Calculation Model and Algorithm Based on Automatic Constant Speed

Ordinary train traction calculation model and algorithm are not suitable for the passenger dedicated rail because the high-speed train sets is very different from the ordinary train. An automatic constant speed train traction calculation model and algorithm were studied in this paper in order to develop a program to calculate the indexes of the high-speed train in running process, such as train＇ s running time, the maximum speed, energy consumption, etc. The high-speed train operation process was divided into four parts： the start and traction accelerate process, constant speed traction process, speed regulation braking process and pull-into and braking process. Each calculation algorithm was established respectively. Finally, the models and algorithms were tested. The results demonstrate that the model and algorithms are effective
