| Abstract: |
| A 3D nonlinear FE model has been established to analyze the effective factors on the wear resistance of 195/60R14 tire.The results show that the distribution of the friction force in the ground contact area will gradually change from greater inside and smaller outside to greater outside and smaller inside as the load of tire increases，and the maximum friction force occurs in the shoulder area；the maximum friction force decreases at first and increases later as the angle of belt cord increases，and the static friction force in ground contact area is symmetrically distributed；and with the same load，the overinflation pressure leads to the increase of the maximum friction force resulting in the premature wear in the middle of crown，and the underinflation pressure leads to the “bridge effect” resulting in the uneven wear in the tread. |
