LEON-T project: Modeling performance of an airless truck tire prototype
Concept of airless tires have gained interest recently. In this work, an airless tire is modeled using finite elements and its radial, lateral and longitudinal stiffness are analyzed. It is found that the radial stiffness of the modeled tire is within the ranges of that of a conventional pneumatic tire, however, the longitudinal and lateral stiffness are 2.5 and 2 times higher, respectively. As future work, the same tire model will be used to study its modal behavior and noise characteristics.
