What is the adhesion coefficient of the mining electric locomotive? What is the difference between it and the coefficient of friction?

The adhesion coefficient is used to calculate the coefficient of the adhesion traction force of the mining electric locomotive, which is defined as the ratio of the adhesion traction force to the adhesion weight of the electric locomotive. Because the power of the mining electric locomotive is still the static friction between the wheels and the track, it is essentially a static friction. However, due to the vibration of the mining electric locomotive when driving, the serpentine motion of the wheelset, the difference in wheel diameter, etc., there are certain differences between them.

There are many factors that can affect the adhesion coefficient of mining electric locomotives, such as the model of mining electric locomotive, axle weight, self-weight, surface cleanliness of wheels and tracks, and so on. A clean and dry track may have a stick coefficient of 0.6 after using sand spread device. But if the track is not clean and there is oil and water, the adhesion coefficient may be less than 0.2.

The above is the introduction of the adhesion coefficient of the mining electric locomotive.
