Theoretical model of non-linear tire slip

Abstract The authors carry out the analysis of research studying the phenomenon of slipping of a wheel with a pneumatic tire. It is established that the increase in the slip angle results in the slip coefficient decrease. The values of the slip coefficient for three types of tires are determined experimentally. The previously proposed analytical expression, which makes it possible to quite accurately formulate the nonlinear relationship of the slip angle with the lateral force acting on the elastic wheel, is clarified.
