Abstract
The dynamics of a wheel moving along a supporting surface is largely determined by friction in the area of its contact with the surface. To determine the force and the moment of the force of dry friction, a model based on the theory of contact stresses of Hertz is used. In the study of specific mechanical systems with dry friction, it is convenient to use approximations of the components of the friction force with simpler expressions. In this paper, two options are proposed for constructing approximate expressions of the components of the friction force using average function approximation.
