Center-Line Deflection of Pneumatic Tires Moving in Dry Sand

Abstract

Tire deflection data were studied from tests performed in the single-wheel test facilities at the U. S. Army Engineer Waterways Experiment Station, Vicksburg, Mississippi. The tests were performed with a smooth 11.00-20, 12-PR tubular tire moving under a 3000-lb load in mortar sand of various strengths and a smooth 9.00-14, 2-PR tubeless tire moving under an 890-lb load in Yuma sand of various strengths. Plots are presented of the path of a point on the center line of the tires relative to a moving and a fixed frame of reference. Representative plots are included to show the effect of slip, soil strength, and inflation pressure on the path and to compare the paths of a point on towed and powered tires.
