Analytical and finite-element study of the role of tread void ratio in terramechanics tyre behaviour

This paper presents an Analytical and Finite Element Study of a rigid plate and a rigid wheel with different tread void ratio patterns interacting with a deformable soil. FE models have been developed in Abaqus® and Drucker- Prager has been chosen as the failure criterion for the soil. The Drucker-Prager model has been replaced by a Mohr Coulomb failure model to be used in analytical modelling of the plate and wheel. A pressure-sinkage equation with invariant parameters is employed in the analytical models. Both longitudinal and lateral grooves are modelled and the improved traction performance of the latter is confirmed. Furthermore, the effect of tread void ratio is studied for both longitudinal and lateral treads.
