Abstract: The interaction between tyre and terrain is the primary factor affecting the efficiency of the ride. The terrain on which the vehicle operates can range between dry or wet road to soil or clayey depending on the vehicle application whether it is off-road or on-road. The terrain properties affect the vehicle ride significantly and thus it is highly important to investigate this aspect. This paper focuses on studying the tyre-terrain interaction from several aspects. The truck tyres used in this study were previously modelled and validated by previous research students. The terrains used are modelled in a virtual performance software Pam-Crash. The terrains include the hard surface (road); soils such as sand and clayey; snow; and water. The tyre-terrain interaction is modelled in Pam-Crash using contact definition and several parameters are collected. The hydroplaning speed of the tyre is studied at different conditions for the inflation pressure, vertical load and water depth. The rolling resistance over several terrains is computed and compared. The soil mixing/layering concept is presented and investigated. This work is a preliminary step for an expanded investigation that will be applied during this research.
