N2 - Based on the tire stiffness test, this paper presents a method for retrieving the tire material parameters with the help of finite element software and optimization software under the condition of reasonable simplification of the tire structure. Based on the radial stiffness and lateral stiffness test, the displacement-load curves of the tire under different tire pressure and different load conditions are obtained. Through the cyclic parameter optimization process, the material parameters of different specifications of tires are inverted. By comparing the experimental and simulation results of radial and lateral stiffness of each tire, the effectiveness of the material parameter inversion method proposed in this paper is verified, that is, the tire finite element model with the material parameters obtained can accurately reflect the overall stiffness performance of the tire. The tire model based on the proposed method can be used for the simulation of radial fatigue test, biaxial fatigue test, 13-degree and 90-degree impact test of wheels, which provides strong support for the evaluation of wheel mechanical properties. In addition, based on the stiffness test and simulation results of different sizes of tires, the influence of tire size, shape and other parameters on the stiffness characteristics is analyzed.
