Abstract
The article presents a new empirical mathematical model for describing the change in the friction coefficient depending on the sliding speed, including such characteristics as the initial intensity of the change in the friction coefficient, the increment in the intensity of the change in the friction coefficient when switching to a new mode, the sharpness of the change in the friction coefficient when switching to a new mode, the value sliding speed corresponding to the minimum “acceleration” of the change in the friction coefficient during the transition to a new friction mode. The validity of the developed mathematical model is shown for the friction of guides made of gray cast iron SCh21-40 in the medium of lubricating oils "Industrialnoe
12 "Industrialnoe 45 "Avtol 18".
