| 摘 要： | 地铁列车自动运行(ATO)系统应保证列车在不同载荷下的区间运行时间均能满足准点性要求。研究了ATO系统两种牵引控制策略(按当前载荷下的最大牵引力控制、按AW3(超常荷载)下的最大加速度控制)在不同的载荷下对准点性能的影响,并分别在最大能力运行场景和节能运行场景下对两种牵引控制策略下的区间运行时间进行了对比。计算结果表明,按AW3下的最大加速度控制这一牵引策略在载荷变化时的区间运行时间波动更小,且其波动范围小于2%,可满足ATO对准点性的严格要求。

| Abstract: | The punctuality of the automatic train operation(ATO)system should be ensured under different train loads.In this paper,the influence of two different traction control strategies(maximum traction force control with current train load and maximum acceleration control with AW3 train load)on the system punctuation is studied,the interval operation times in the scenarios of maximum capacity operation and energy-efficient operation are compared.The results show that,the traction method of maximum acceleration control with AW3 train load can achieve less run time fluctuation(within 2%range),therefore satisfies the ATO system with strict punctuality requirement. |
