This book was released on 1972 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study reported herein was conducted to determine whether the sand mobility number that had been developed for circular-cross-section tires operating in a particular coarse-grained, air-dry soil could be used to predict the performance of rectangular-cross-section tires in the same or a second coarse-grained, air-dry soil. Five rectangular-section tires were tested in each of two coarse-grained soils, a desert sand from Yuma, Arizona, and a mortar-type sand from a river deposit near Vicksburg, Mississippi. The data collected in these tests were compared with relations previously developed from tests with circular-section tires in air-dry Yuma sand. Analysis of test results showed that the existing sand mobility number can be used to predict the performance of rectangular-section tires in both test sands. (Author).

This book was released on 1966 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report examines the effects of tire deflection, tread, carcass stiffness, construction, speed, and slip on tire performance in a dry sand. Laboratory tests results indicate that for best performance in a dry sand a tire should be highly deflected, smooth, and of diagonal-ply construction. Variations in carcass stiffness have negligible effects on tire performance when comparisons are made at equal loads and deflections. It was concluded that the performance of pneumatic tires in sand is affected by speed; however, the extent of this influence was not wholly determined. Logical, orderly relations are shown between slip and several independent and dependent variables--wheel load, soil strength, pull, and sinkage--both at the towed and the maximum pull points. A direct relation is shown between the pull developed by a full-scale 4x4 vehicle and that developed by a single wheel in multiple passes. Good agreement was attained in this relation for both Yuma (desert) and mortar sand. Significant differences in tire performance registered in Yuma and mortar sands at corresponding levels of soil strength (as measured by cone index) prompted a study of the physical characteristics of the two soils. This study revealed notable differences in the strength characteristics of Yuma and mortar sands that explain a portion of the differences in tire performance in the two sands.

This book was released on 1967 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was made of the effects of various testing techniques on the performance of pneumatic tires operating in an air-dried desert sand and a nearly saturated fat clay. Tests employing both controlled-slip and controlled-pull techniques were conducted with single-wheel dynamometer carriages. The results are presented in the form of graphs with emphasis placed upon the pull-slip and torque-slip relations. For the conditions tested, wheel performance was found to be independent of testing techniques, with one exception; consistent differences were noted between the results of programmed-increasing- and programmed-decreasing-slip tests. However, this disagreement occurred only for a narrow range of slip (approximately -10 to +10%). Careful and complete analysis of a dynamic test system must be made to determine the forces that actually represent the wheel performance. A brief analysis of the horizontal forces acting on the test dynamometers is given to emphasize this point, particularly with regard to differences between pull-slip and drawbar pull-slip relations. It is shown that because of the inability always to attain a stable condition in controlled-pull tests, controlled-slip tests are better for defining pull-slip relations. (Author).
