| Abstract: |
| In this study，a finite element model of 11.00R20 truck and bus radial tire with complex tread pattern was established by using Abaqus software.During the finite element analysis the mechanical behavior of rubberlike materials was described by Yeoh model due to nonlinear physical characteristics，large geome-tric deformation and nonlinear contact boundary of the material. Moreover，the steel cord was modeled by embedded surface element with Rebar.Then the reliability of the model was verified by experiments.The re-sults showed that，the vertical stiffness of the tire increased with increase of deflection，and finally closed to a constant value.As for pressure distribution in the contact patch，the larger pressure was located at the edge of the pattern blocks.The footprint shape and area predicted by numerical simulation were in good agreement with experiment results.In the ground-contact area，the circumferential rebar force of carcass was lower in the middle of the footprint compared with that of the outer contact patch，and then the rebar force of carcass gradually decreased away from the ground-contact area. |
