| Abstract: |
| Taking 16.00R25 all-steel off-the-road radial tire as the object，the finite element models of the complex tread pattern tire and smooth tread tire were established.The effectiveness of the two models was verified by comparing simulation results and measured results，and the influence of the complex tread pattern on simulation results of the tire was studied based on different drum sizes.The simulation results showed that the differences between the simulated values and measured values of the inflated peripheral dimentions of two models of the tires met the engineering error requirements.The simulation results of the footprint of the complex tread pattern tire were closer to the measurement results.Compared with the smooth tread tire，the torsional stiffness，lateral stiffness and radial stiffness of the complex tread pattern tire were all reduced.The change trends of the mechanical properties of the complex tread pattern tire and the smooth tread tire were consistent under different operating conditions，but the variation amplitudes were different. |
