Un modello per lo studio dell'usura degli pneumatici: confronto numerico-sperimentale ed effetto dei parametri costruttivi


Due to their many economic and ecological implications the possibility
to predict tyre wear is of major importance to tyre manufacturers, fleet
owners and governments. Based on these observations, in 2000 a three-year
project named TROWS (Tyre and ROad Wear and Slip assessment) was started.
One of the TROWS objectives was to provide a tool able to numerically
predict tyre global wear as well as to qualitatively determine the wear
distribution. The proposed methodology combines a mathematical model of
the tyre with an experimentally determined local friction and wear law.
Thus, tyre abrasion due to each single manoeuvre can be determined.
Full-scale experimental tests were carried out with two Peugeot 406 cars
on a public road course in Italy. Each car was equipped with a different
set of tyres: one car was equipped with four all-season tyres (from now
on called A tyres) and the other car was equipped with four winter tyres
(from now on called B tyres). Both sets of tyres had a 195/65 R15 size.
The collected data was used to validate the model. The methodology proved
to give qualitatively good tyre wear predictions..
