The invention discloses a locomotive traction upper limit amplitude limiting method, which comprises the following steps of: obtaining an adhesion coefficient setting value by adopting a direct reasoning calculation method according to an environment temperature, a weather state and a rail object landing state, and adaptively adjusting an adhesion coefficient, so that the maximum traction limit of a locomotive can be changed in real time along with the change of road conditions of a road section; locomotive traction is carried out under the condition that wheel set idling does not occur as much as possible. When idling of the wheel pair cannot be avoided, calculating an idling risk value by adopting a nonlinear mathematical expression according to the creep degree change rate and the creep degree, judging whether the locomotive wheel pair idles or not, and determining whether to perform idling traction force control on the locomotive traction force subjected to the upper limit amplitude limiting control or not according to an idling judgment result. Multi-factor comprehensive judgment is achieved, and idling judgment and idling traction force control are more comprehensive and accurate.
一种机车牵引力上限限幅方法,依据环境温度、天气状态和轨道着物状态,采用直接推理计算的方法得到粘着系数整定值对粘着系数进行适应性调整,使机车的最大牵引力限制能够随路段路况的变化实时改变,尽量在不发生轮对空转的情况下进行机车牵引。当不能避免轮对发生空转时,采用非线性数学表达式依据蠕滑度变化率和蠕滑度来计算空转风险值,判断机车轮对是否发生空转,并依照空转判断结果决定是否对进行上限限幅控制后的机车牵引力进行空转牵引力控制,实现多因素的综合判断,使空转判断和空转牵引力控制更为全面准确。
