SCALED VEHICLE MOBILITY FACTORS (SCALE MODEL TIRES IN SNOW)

Abstract

Tests were conducted in snow with six reducedscale tires. The tires covered a wide range of width-to-diameter ratios. The results are expressed in dimensionless terms and are applicable for a range of vehicle sizes and weights as well as a range of dry snow conditions. Tests described in previous reports have covered the flotation type of performance. Tests described herein cover the performance of two types of tires for the ground-supported (limited snow depth) type of performance and, also, the results of additional flotation tests. The complete flotation data, including that from previous years' tests, are summarized and further analyzed. Present data are limited to 4x4 vehicles with equal weight distribution. The possibility is shown that data for vehicle tests in sand can be interpreted in terms of performance in snow. Results of a preliminary snow survey, which can be used to predict vehicle performance in subarctic, below-thetree-line snow regions, are shown.
