| Abstract: |
| A three-dimensional non-linear finite element model of 9.00-20 16PR bias truck tire was established，with which the effect of the cord angle on the deformation，stress-strain behavior in the ground contact area of tire at the same inflation pressure and deflection was investigated.The results showed that the cross-sectional width of tire，the inter-laminar shear stress in cord plies of bead area，and the first principle stress and strain in cord plies increased，but the overall diameter of tire and the maximum vertical contact stress and friction stress decreased as the cord angle of carcass plies increased. |
