Abstract
With our approach we can simulate the dynamics of a tyre tread block concerning displacement of the gravel, external and self-contact of the tread block’s lips. The simulation can help to investigate contact phenomena of a rolling tread for different surfaces and materials.

N2 - One focus of modelling the movement of vehicle tyres on the road is the contact of the tread with the road surface. The tread can consist of many blocks, that vary in form and length and can exhibit a siped structure to improve the traction of the tyre on the road, especially for winter tyres. The rotation of the tyre leads to periodical impacts of each tread block into the road surface, which is often uneven. The road can have loose gravel on it or can be covered with grit (icy roads). To simulate the dynamics of a tyre on a gravel road, we suppose to focus on a single tyre tread block. This block gets into frictional contact with the surface, the granular material and also with itself, when the block is siped and the individual lips touch each other. In our model these contact configurations are formulated as linear complementarity problems. The tyre tread is made of an elastomer material, which possesses viscoelastic behaviour.With our approach we can simulate the dynamics of a tyre tread block concerning displacement of the gravel, external and self-contact of the tread block’s lips. The simulation can help to investigate contact phenomena of a rolling tread for different surfaces and materials.
