| Abstract: | In this paper finite element analysis model of 9.00R20 radial tire is built and the static stress strain distribution in the contact area is analyzed. The material and geometric nonlinear property and the anisotropy property of composite materials as well as the incompressibility of vulcanized rubbers are all taken into account. The effects of such factors as quantity of deflection, inflated pressure and friction coefficient on the stress distribution in the contact area are also given. All these results are of significance for engineering design. |
