Abstract:
The existing tire models are basically of three kinds: essentially empirical (“magic formulas”), or mixed empirical/analytical, or extremely complex theoretical models almost useless in practical situations. The model here proposed does not require any empirical data, and presents a simple theoretical approach very suitable to use in project and analysis of real suspension systems.This paper presents a physical and mathematical model for the mechanical behavior of pneumatic car tires, in the particular case of lateral loading. It is a theoretical model, in the sense that it does not require any empirical data. It is based on the perfectly flexible and quasi-inextensible membrane theory.The next step will be to compare the calculated results from this model with measured data to validate this model.
