This paper investigates the tire-terrain interaction for a Mixed Service Drive (MSD) truck tire with two different solid rubber material definitions using a Finite Element Analysis (FEA) virtual environment. An MSD truck tire sized 315/80R22.5 is designed with two different solid rubber material definitions: a legacy Hyperelastic Solid Mooney-Rivlin material definition and an Ogden Visco-Hyperelastic solid material definition. The popular Mooney-Rivlin is a material definition for solid rubber simulation that is not built with element elimination and is not easily applicable for thermal applications. The Ogden Visco-Hyperelastic material definition for rubber simulations allows for element destruction and is more suited for designing tire wear models. Both the Mooney-Rivlin and Ogden-equipped MSD truck tires are subjected to a static vertical stiffness test to validate their static domain characteristics.
