Simulation of Static Tyre–Pavement Interaction Using Two FE Models of Different Complexity

The aim of this research study was to analyse the approaches for establishing a spatial model radial truck tyre, based on finite element method, in order perform realistic analysis static as well dynamic tyre–pavement interactions. A complex rubber tyre having large number elements formulated combining current state-of-the-art modelling techniques and, from that model, simplified smaller derived. proved be useful only loading, because its high computational demand, while also suitable modelling. two models different numbers were compared by analysing contact areas and stresses. Our results indicate basic idea not changing material characteristics simplifying rebuilding carcass using composite shell elements, did prove satisfactory direction. given do describe behaviour but, rather, diagonal regarding On contrary, when stresses strains road pavement structure, provided similar practice. Based our comparison calculations, applying average pressure q at points 5–8 cm depth, can used any elastic-layer theory-based software.
