摘要:
地铁列车牵引计算往往沿用铁路列车的牵引计算方法，忽略了地铁车辆对控制加速度的“缓变式”处理过程，给牵引计算的控制加速度、速度和运行时间计算带来偏差。给出了考虑冲击限制情况下，地铁列车最大能力运行及节能运行时的牵引计算算法，并采用实际列车和线路数据对算法进行了验证。计算结果表明，考虑冲击限制的地铁列车牵引计算算法可以提高牵引计算中列车速度、加速度和时间的仿真精度，使速度和加速度的仿真计算结果更符合地铁列车运行实际，区间运行时间的计算精度可提高2%以上。
Abstracts:
The traction calculation of metro trains is usually based on the method of railway train traction calculation, and the jerk limitation process of the control acceleration of metro trains is ignored, which brings deviation to the calculation of control acceleration, speed and running time. The traction calculation algorithms of flat-out run and energy-saving operation were given considering the jerk limitation of train, and the algorithm was verified by using the actual train and line data. The calculation results show that the traction calculation algorithm of metro trains considering jerk limitation can improve the simulation accuracy of train speed, acceleration and time in the traction calculation to get more realistic results, and the calculation accuracy of interval running time can be increased by more than 2%.
