Abstract

Most tyre models used in vehicle dynamics simulations are parameterised with data obtained on a flat-track test rig, where the tyre is commonly driven on sandpaper. The resultant models are typically very accurate at low to medium slip conditions. At high slip, the prediction of forces and moments of a tyre rolling on surfaces other than sandpaper is less reliable as this condition is dominated by the rubber-road friction characteristics. To extend the validity of tyre models derived from sandpaper surface measurements to road surfaces, this paper explores the use of frictional behaviour of tread rubber obtained with a purpose-built rubber friction measurement system. Since rubber friction depends on many variables, tests have been carried out under controlled conditions in order to obtain accurate and repeatable data. Friction measurements were performed on sandpaper and incorporated into a brush-type tyre model to recreate the flat-track measurements of the full tyre. Preliminary results indicate the benefits and potential of detailed knowledge on the frictional behaviour for accurately modelling tyre forces and moments.
