The objective of this paper is to present a high-fidelity physics-based approach to accurately and reliably predict the vehicle response measures, which will allow for independent testing and validation of the model components such as soil type, tire/track, powertrain system, vehicle suspension system, and traction control system rather than having to experimentally measure the response for each vehicle configuration and soil type. The modeling approach is based on (i) a seamless integration of multibody dynamics and discrete element method (DEM) solvers, and (ii) using a Design-of-Experiments (DOE) to predict the off-road soft soil mobility of ground vehicles on large-scale terrain maps.
