Static in-tire circumferential strain signature using Rayleigh-scattering fiber optic technology : Preliminary results

Résumé

The paper presents both the modeling and the experiment to measure the longitudinal static strain over the inner perimeter of a tire. These measurements are expected to help at updating some unknown geometrical and mechanical parameters of tires for achieving more accurate simulations under conventional CAO software (namely, Solidworks). Compared to the literature, a distributed fiber optic sensing is used to measure the inner liner tire strain profile along the perimeter. Based on the Rayleigh scattering, this technology provides a fine spatial resolution, namely, less than 1 cm. The preliminary results show the typical Mexican-hat-like circumferential strain distribution and the contact patch length. Both quantities are shown to be related to the static load.
