The invention relates to a locomotive wheel rail adhesion coefficient setting value setting method, which comprises the following steps of: reasoning according to an environment temperature and a weather state to obtain a weather environment factor value, then reasoning according to a track object landing state to obtain a track object landing factor value, and taking the product of the weather environment factor value and the track object landing factor value as the locomotive wheel rail adhesion coefficient setting value. The setting value of the adhesion coefficient is used for calculating the adhesion coefficient, and the upper limit amplitude limiting control is performed on the traction force of the locomotive according to the calculated adhesion coefficient, so that the maximum traction force limit of the locomotive can be changed in real time along with the change of the road condition of a road section, and the idling condition of a locomotive wheelset is avoided as much as possible.

    一种机车轮轨粘着系数整定值整定方法,首先依据环境温度和天气状态推理得到天气环境因子值,然后依据轨道着物状态推理得到轨道着物因子值,取天气环境因子值与轨道着物因子值的乘积为机车轮轨粘着系数整定值。粘着系数整定值用于进行计算粘着系数的计算,再依据计算粘着系数对机车牵引力进行上限限幅控制,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,尽量避免机车轮对空转的情况发生。
