摘　　要：为改善地铁车辆在空转状态下的黏着力波动幅度,提出了一种阈值动态调整方法。该方法通过对一定时间段黏着力的波动情况统计,及时调整检测阈值,能更准确检测出空转状态,并及时调整黏着力。试验结果表明,该阈值动态调整方法可以有效地提高地铁车辆黏着控制性能,减小黏着力波动幅度,提升列车的运行平稳性和乘坐舒适性。In order to improve the metro’s fluctuation of adhesion force in the slip state,a new method of dynamic adjustment of detection threshold for metro anti-slip was put forward.The method could adjust the detection threshold in time,detect the slip state effectively,and adjust the adhesion force in time through the statistics of the fluctuation of adhesion force for a certain time period.Experimental results show that the dynamic threshold method could effectively improve metro’s adhesion control performance,reduce the fluctuation of adhesion force,and improve the smoothness and comfort of the train.
