Locomotive wheel rail adhesion coefficient setting value setting method

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
