The invention discloses a subway train slip prevention method based on longitudinal load, which comprises the following steps: S1, grouping trains, and distributing braking force; s2, a creep rate threshold is set, and the current train wheel rail state is judged according to the creep rate; s3, under the condition that the creep rate is smaller than the creep rate threshold, the current train wheel rail state is judged through the longitudinal load; and S4, corresponding braking force is applied according to the current train wheel rail state. According to the method, the maximum friction force of the track is accurately obtained in real time, the train is prevented from slipping in advance, and the subway operation efficiency is improved.

    本发明公开了一种基于纵向载荷的地铁列车打滑预防方法,包括:步骤S1,将列车分组,并分配制动力;步骤S2,设置蠕滑率门限,根据蠕化率判断当前列车轮轨状态;步骤S3,在蠕滑率小于蠕滑率门限的情况下,通过纵向载荷判断当前列车轮轨状态;步骤S4,根据当前列车轮轨状态,实施相应的制动力。本发明通过实时精确地获得轨道最大摩擦力,提前避免了列车发生打滑,提高了地铁运营效率。
