ERDC's Cold Regions Research and Engineering Laboratory (CRREL) uses a three-dimensional model of a deformable tire on a deformable surface to predict vehicle mobility, terrain deformation under vehicle loads, off-road tire design, and tire specification for specific off-road machinery. CRREL studies focus on the vehicle/terrain interface for wheeled, tracked, air cushion, and hybrid vehicles operating on ice, deep and shallow snow, and thawing soil terrains. These studies are relevant and timely because vehicle
mobility on unpaved surfaces is important to the military and for agriculture, forestry, mining, and construction industries.
