Dynamic Load Effects On Thrust Components Along The Soil-Tire Contact Zone
ABSTRACT Tractive thrust components across the width of an 18.4R38 radial-ply tire were examined to determine how the tire generated thrust in loose and compacted soil conditions at each of four levels of dynamic load. The tire developed thrust more uniformly across the lug face in the loose soil conditions than in the compacted soil conditions. Increased dynamic load resulted in significant increases in the thrust at the tire centerline and lug edge positions. The thrust developed at the center of the lug was not significantly affected by increasing dynamic load on the compacted soil conditions.
