Tracked vehicle – soil interactions were modeled and analyzed under multiple design scenarios for a notional path clearing tracked vehicle as part of this exploration in assessing the capabilities and limitations of the state-of-the-art in tracked vehicle dynamics modeling and simulation over soft-soil terrain.  The multiple design scenarios consisted of different path clearing implements attached to a tracked vehicle chassis with either two or four road wheels per side and with either a segmented track or a band track.  The simulations were conducted over both clay and sand.   One path clearing implement was a roller and rake combination. The roller pressured the soft soil while the rake sheared it. The other path clearing implement was a quickly rotating flail system that cleared a definitive path by impacting and flinging the soil away.  Geotechnical forcing functions implemented Coulomb’s lateral earth pressure theory and Terzaghi bearing pressure models to compute the forces at the soft-soil – implement interfaces.  Bekker pressure-sinkage models determined the resultant soft-soil – track forces.  The multiple vehicle designs and soil combinations were simulated over discrete events and compared by means of load and acceleration time histories derived from these complex multi-body dynamics simulations.  Performance sensitivities to track design properties were studied in addition to the effect of contact stiffness between track, road wheels, idler, and sprocket. Unique modeling and simulation methods to stretch the capability of the current state-of-the-art contribute to the overall discussion.
