The in-plane deformation of a tire carcass: Analysis and measurement

(in lingua inglese)

In this paper, the in-plane deformations of the tire carcass are studied with tire model simulations and experimental tire sensor measurements. The flexible ring model was used to analyze the in-plane tire deformation under different vertical and longitudinal forces. The simulated in-plane tire deformations match the deformations measured through the optical tire sensor. Indicators from the optical tire sensor measurements are proposed and demonstrate good correlations with the forces applied to the tire. It is found that the radial deformation of the tire carcass provides information on both the longitudinal and vertical forces acting on the tire.
