Abstract
Abstract : The validity of the assumption of uniform pressure distribution under a pneumatic tire was checked in this study. Measurements of pressure distributions under pneumatic tires at their interface with firm surfaces and soft soils, previously made at the U.S. Army Engineer Waterways Experiment Station, were used. Two tires (11.00-20, 12-PR, and 12.22.5, 12-PR) tested at three inflation pressures (104, 207, and 414 kN/square meters) and under wheel loads ranging from 6670 to 20,030 N were investigated. Stresses and displacements were computed by the theory of elasticity for various depths in the half-space under loading conditions: measured, assumed uniform, assumed parabolic, and assumed conical pressure distributions. Generally, the assumption of uniform pressure distribution was found to be unreasonable in cases of high- inflated tires on a hard surface and on sands, but it was found acceptable in the other investigated cases, including those for clay surfaces. However, the assumption of parabolic pressure distribution was found to be more realistic than that of a uniform one for high-inflated tires on sands and for low-inflated tires with light load on loose sand.
