A dynamic vehicle model, simulating both the vehicle dynamics and the wheel-soft soil interaction, is presented. Equations of motion are presented for a two-dimensional, six-degree-of-freedom vehicle. Relationships for forces and moments on the vehicle and its wheels due to wheel-soil interaction are developed as functions of normal and shear stresses in the soil. Both the rigid wheel and flexible wheel cases are addressed. Current state-of-the-art relationships among shear stress, normal stress, wheel sinkage, and wheel slip are used. Parametric studies are used to assess the qualitative validity of the model. While experimental data does not exist, comparison of the results of the simulation with known information from the field of off-the-road mobility indicates the model to be valid. (Author)
