The simulation of the dynamic rolling contact opens numerous benefits by saving development time and costs. In this chapter, fundamental algorithms for the numerical efficient simulation of rolling rubber wheels are shown. The exposed model is validated by steady and unsteady experimental investigations. For this purpose, a moving test rig has been developed and built up. Outcomes of steady rolling experiments are shown firstly. The resulting friction characteristics reveal the behavior of different elastomers in contact with a glass surface. Furthermore, the dynamic dependency of the tangential force on the start and the target level of a preceding slippage-step is investigated. Based on the dynamic behavior of the rolling contact observed in the measurements, a mechanical model for simulation is presented. The 2D model includes a structure model of the wheel body, as well as a contact formulation in normal and tangential direction reproducing sticking and sliding behavior, respectively. The results of the simulation are opposed to the measurements done with the moving test rig.
