“…Thus, power loss due to friction in contact of an elastic wheel with a rigid base, due to implementation of tangential force in the contact, is determined by equation: Рfr = FxxV (19) in which values Fx and x are substituted with their signs (Fx and x are positive for the leading rolling mode and negative for the idle and braking).…”

Among the large number of studies aimed at solving the problems of determining the kinematic and force characteristics of a wheel when it rolls under various operating conditions, one can highlight analytical works based on the mechanics of interaction of an elastic wheel with a supporting surface. This approach used in this article, from the analysis of the phenomena occurring in the contact of an elastic wheel with a rigid base, makes it possible to consider general issues of the mechanics of wheel rolling. This made it possible to obtain for the considered friction pair “elastic wheel – supporting surface” relatively simple dependencies that make it possible to determine the longitudinal force and power of friction losses in contact, the relative speed loss (slippage) of the wheel, the coordinate of the boundary of the adhesion and sliding areas on the contact area, the drag coefficient rolling, the coefficient of tangential elasticity of the wheel, evaluate the legality of using various accepted laws of pressure distribution in contact.

“…Since the implementation of forces and moments applied to the wheel occurs in the contact zone of the wheel with the supporting surface, the analytical determination of the force and kinematic parameters of the wheel should be based on the consideration of contact phenomena occurring in the contact zone [16,[22][23][24][25][26][27][28][29][30][31][32][33][34].…”

The implementation of forces and moments applied to the wheels of a vehicle occurs in the zone of contact of the wheels with the supporting surface, and therefore the analytical determination of their force and kinematic parameters should be based on consideration of the phenomena occurring in contact. One of the directions for solving these problems is based on a technique based on the theory of preliminary displacement of wheel surface elements in the contact zone with the supporting surface and dividing the contact area into adhesion and sliding zones, which makes it possible to take a new approach to the consideration of wheel rolling mechanics. The use of this technique makes it possible to obtain relatively simple equations for such power and kinematic parameters of the wheel as the coefficient of rolling resistance, the coefficient of tangential elasticity of the wheel, and hysteretic losses in the wheel material. The derived equations contain a small number of parameters that can be easily determined experimentally and are convenient for both theoretical and practical use. Comparison of theoretical and experimental results with studies of other authors shows their relatively small discrepancy, which confirms the validity of the research methodology used, as well as the assumptions made.

“…In [20,21,22] equations were derived to calculate the magnitude of the tangential force arising in the contact of the wheel with the drum, the relative loss (slippage) of wheel speed, the power of friction losses in the contact and hysteresis in the wheel material, as well as the rolling resistance factor of the driven wheel. At the same time, the question of the point of application of the normal force in contact with the drum and, accordingly, the arm of this force relative to the wheel axis (Fig.…”

Evaluation of the rolling resistance of car tires is now often performed on drum stands like car tests. This necessitates the study of the mechanics of interaction between the wheel and the drum in order to determine its force and kinematic characteristics, including the values and points of application of tangential and normal forces in contact with the drum. These problems can be solved taking into account that the mechanics of elastic wheel rolling on a drum is the same as when rolling on a flat rigid support surface. In this paper, from consideration of the mechanics of interaction between an elastic wheel and a drum, using the equations of power balance and force equilibrium of the wheel, the equations for determining the point of normal reaction in contact and its arm relative to the wheel axis during its rolling along one and two drums have been derived.. These dependencies have a simple form and can be applied when considering the rolling of both a single wheel and the car as a whole on a drum stand.
