摘 要: 为解决基于离散控制的列车牵引计算问题,设计以离散控制为基础的通用列车牵引计算模型。通用列车牵引计算模型以多质点列车模型为基础,根据列车运行过程分为3个主要过程:起动和加速过程、中间运行过程及进站制动过程。根据均衡速度法确定各坡段的目标速度,据此确定工况选择问题。在此基础上,设计开发了普通离散控制模型的列车牵引计算系统,测试表明:该模型合理、有效。
关 键 词: 铁路运输;列车牵引计算;离散控制;多质点列车模型;工况选择

Abstract: In order to solve the discrete controlled train traction calculation problem, the paper sets up a general discrete controlled train traction calculation model. The model includes multi�particle train model and three main operation processes. The processes are start and acceleration process, moving process and braking process. The paper chooses balance speed of train to shift gears. Energy consumption is deduced by reducing unnecessary brake. According to these analyses, train traction calculation program is built up. Test results indicate that the model is effective and reasonable.
Key words: railway transportation; train traction calculation; discrete control; multi�particle train model; operating mode selection
