Abstract: This paper focuses on the impact of tyre configuration on the tyre-terrain interaction characteristics. Two truck tyre models are developed utilising the finite element method (FEM) and validated in static and dynamic response in a computational environment. The first truck tyre model is the Regional Haul Drive with dimensions 315/80R22.5 which is used in the dual configuration for tractor semi-trailer applications. The second truck tyre model is the Super Single X One XDA size 445/50R22.5 that is used in a super single configuration. The terrain models are developed using a smoothed-particle hydrodynamics technique and are validated using published data. Both tyres are tested under various operating conditions including on-road and off-road operations, loading, and tyre speed. This study investigates the tyre-terrain characteristics of both tyres and the effect of the variation of moisture in the sandy loam soil.

Keywords: FEM; finite element method; dual tyres; super single; smoothed-particle hydrodynamics; tyre-terrain interaction.
