Abstract:
      A three-dimensional finite element model of tire-pavement contact was established for 11. 00R20 truck and bus radial tire using Abaqus software, and the change of tire-pavement contact stress under different states was simulated by coupling three variables which were tire vertical load，working condition and cornering angle. Therefore, the changing trend of tire ground contact stress under the coupling effect of different variables was obtained by analyzing the stress nephograms of tire ground footprints under different states. This research broke through the limitations of the conventional simulation results under static or uniform speed conditions，improved the reliability of calculation，and could guide the research works on tire-pavement contact stress，pavement protection and tire optimization design.
