The problem of elastic sliding in the ‘wheel — road surface’ contact is considered. A mathematical surface interaction model is developed. The model presented here suggests that the road surface deformation processes can be neglected. The wheel is modeled as a set of elastic rim sectors mounted on an elastic disc. The model dynamics is mainly influenced by the interaction force of the rim sectors with the wheel center, the intersectional interaction force, and the contact surface interaction force. The experimental studies using numerical simulation methods are conducted. It is discovered that there is a dependence of the stalling load value on the other wheel properties. The obtained results are of interest for solving problems on the wheel motion control to prevent the contact disruption. The used holistic approach allows identifying the emergence that influences the overall system trajectory.
