摘要
阐述了列车牵引计算的基本原理,给出了牵引系统各参数的计算公式,并通过在每个速度区建立的电机牵引力、电机电流和电机电压对速度的数学模型,动态分析了运行中各点的情况.最后以哈尔滨地铁1号线项目为例对反映列车运行性能的各个指标进行了计算和仿真,并进行了牵引电机的选型,项目执行结果证明了选型的合理性.
The fundamental principle of the traction system calculation is described, and the formula of the traction system parameters are given. The characteristics of different working points are dynamically analyzed through setting up the mathematical model of traction force, motor current and motor voltage to speed in different speed areas. Computation and simulation are conducted to obtain the target data for train running and select the type of motor,which demonstrates the feasibility of the selection.
