Kinematic Modeling and Analysis of the Tire Model with the Analytical Elastic Foundation for the Heavy-Loaded Radial Tire

The study investigates the analytical sidewall stiffness and analytical elastic foundation modeling of a radial tire with a large section ratio for a heavy load vehicle. A proposed tire model with a flexible belt on an elastic analytical stiffness foundation is investigated. the analytical multi-stiffness function of a large section ratio sidewall is derived by combining the membrane feature caused by inflation pressure and the structural deformation caused by sidewall curvature. The experimental and theoretical results indicate the following: ① the bending characteristic of the belt within 0-180 Hz can be featured with the flexible belt on an elastic analytical stiffness foundation tire model. ② the multi-stiffness function of the curved sidewall is related to the inflation pressure, structural curvature, and material properties. ③ the inflation pressure effects the pre-tension force of the belt and the pre-tension membrane feature of the sidewall.
