Abstract: The research conducted in this study deals with the development of a simplified brush-based tyre model for on-road simulation, together with a simplified off-road wheel/tyre model. The on-road tyre model is developed based on data collected by NHTSA throughout the years, while the off-road tyre model is developed based on observations of experimental data and photographic evidence collected by various terramechanics researchers within the last few decades. The principle behind the model revolves around the integration of the stresses at the contact interface and has its basis in terramechanics. The model was parameterised from test data to acquire static and dynamic friction coefficients, cornering and longitudinal stiffness, as well as camber stiffness. The results are compared with test data and show good correlation. This paper is the first of a series of three papers on the modelling tyres for both on- and off-road operations.
