ThermoTyre: tyre temperature distribution during handling manoeuvres

Abstract

Based on the Fourier heat equation, an analytical model to determine the tyre temperature distribution, during its employment, is described. The model, called ThermoTyre, analyses the tyre thermodynamic behaviour. The model is in one-dimensional form and is characterised by a low computational load. Therefore, it lends to be easily integrated with interaction models in order to execute handling analyses. The work takes advantage of the cooperation with the Bridgestone Technical Center Europe that produces expertise and experimental data. After an analytical model description, simplifying hypothesis and boundary conditions are illustrated. Finally, the comparison between experimental data and theoretical results are shown.
