Automobiles with ground effect is realized through the tire, the mechanical characteristics of the tire many important properties of the automobile, its stiffness characteristics have a major impact on the vehicle performance, when conducting vehicle performance analysis, the stiffness of the tire parameters is essentialthe.
The tire has a complexity of the geometry and material diversity, the study of the mechanical properties of tire put a lot of effort to establish a variety of tire characteristics testing device and analytical models. The tire analysis model can be roughly divided into two kinds: one is the mathematical description of the tire structure and transformation mechanism of the machine, the establishment of shear force and back to the positive moment and the corresponding parameter as a function of the theoretical model; another is through the large number of tests data regression analysis, the mechanical properties of tires with fitting parameters formula effectively demonstrated by empirical or semi-empirical formula. The models have in common is a lot of assumptions, the tire structure and materials will also tire simplified linear model.
