An experimental and simulation study on static tire enveloping stiffness
Three bump sizes, six pressures and five placement angles of bump were used in this paper to conduct enveloping stiffness experiments. The experimental tire displacement-load curves showed that the enveloping stiffness of the tire under the same pressure did not change with changes of the bump size....

| Sumario: | Three bump sizes, six pressures and five placement angles of bump were used in this paper to conduct enveloping stiffness experiments. The experimental tire displacement-load curves showed that the enveloping stiffness of the tire under the same pressure did not change with changes of the bump size. And the enveloping stiffness of the tire were changed with changes of pressures and placement angles; Models consider pressure and placement angle of bump were established respectively, and established a model consider pressure and placement angle simultaneously by least squares, those models can be used to estimate enveloping stiffness force without experiments. Abaqus finite element software simulations showed that the stress distribution in the tread is H-shaped and the deformation distribution in the tread is oval; By analyzing the force distribution of the ply found that the distribution of force changes with the change of placement angles. The lateral displacement(U1) of the belts increases linearly with increasing angle. The end of cord is prone to failure at 0° and 45°, and the cord near middle of ply is also prone to failure at all angles. |
