Abstract:

Proposed in this paper is a three-dimension（3D） finite element model of 175/65R14 tire,in which the tread pattern is ignored and the Rebar element model is used to simulate the composite cord-rubber materials.Then,by taking into consideration the nonlinearities in the aspects of rubber,geometry and contact,the deformations of the tire under radial load,lateral load,longitudinal load and torsion torque are respectively analyzed with the finite element software ABAQUS,and the characteristics of five kinds of stiffness of the tire are simulated.The results indicate that the simulated characteristics of radial,lateral,longitudinal and coating stiffness accord well with the experimental ones,and that the simulated characteristic of torsional stiffness and the experimental one are of the similar tendency though the former is less than the latter.It is thus concluded that the proposed simulation model is effective.
