Abstract:

This interim report covers tests to determine correlation between scale-model and full-size, 4 x 4, pneumatic-tired vehicles operating in sand. Test results demonstrate that the mobility performance of prototype wheeled vehicles can be accurately predicted by tests on scale-models using the techniques described. Tire selection data for 4 x 4 vehicles are presented covering the full range of sand strengths found in nature, tire loadings from 50 lb. to 50,000 lb., and sizes from 2 to 10 in outside diameter and 020 to 1.00 in widthdiameter ratio. Means for estimating sand strength for design purposes are also indicated. A simple relationship between tire performance in sands and dry snows is also demonstrated. Author
