Аннотация:ABSTRACT ABSTRACT On the basis of previous research papers, an enhanced tyre model is presented which could be useful both for vehicle dynamics analysis and for tyre design. The physical phenomena involved in tyre-ground force generation are described mathematically in a semi-analytical form. Given the main mechanical parameters of the tyre, the friction coefficients and the running conditions, the model returns the values of the forces generated at the tyre-ground interface either at steady- or at transient-state condition. Comparisons between experimental and computed data have been performed with satisfactory results.
