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).

Available in PDF, EPUB and Kindle. Book excerpt: Three pneumatic tires were used in a laboratory study to compare the performance of dual wheels at zero spacing with the performance of single wheels and to determine the influence of tire spacing on dual-wheel performance. One-pass tests were conducted on air-dry, medium dense to very dense sand. The data were analyzed for powered wheels in terms of pull, torque, and sinkage coefficients and of efficiency, all at 20 percent slip, and for towed wheels in terms of towed force coefficients. The existing WES performance prediction system was used in both cases. Results showed that a powered dual wheel at zero spacing, considered as two wheels sharing equal load and exhibiting equal performance, outperformed a single wheel with the same characteristics as each wheel of the dual-wheel configuration. The performance of powered dual wheels decreased with increasing wheel spacing until the two wheels performed like single wheels. This critical spacing was reached when it became two to three and one-half times the width of one of the wheels. A dual wheel at zero spacing, considered as one wheel, performed practically the same as a single wheel with the same characteristics of the dual-wheel configuration; however, the dual wheel with zero spacing performed more efficiently than the single wheel over a certain range of load, deflection, and soil strength combinations.

This book was released on 1965 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: A total of 709 tests performed with single pneumatic tires in Yuma desert sand placed in movable sand bins in the laboratory are analyzed. Basic plots are presented to show the correlations obtained between individual variables. Representative cross plots are included to show the effects of tire width and diameter and to illustrate the relative effectiveness of the various tires tested. Initial steps in the development of a numeric that will define a single relation between dependent and independent variables for all tires and test conditions are reported.
