Available in PDF, EPUB and Kindle. Book excerpt: This study was directed toward obtaining a fundamental understanding of the tire-soil system from a qualitative investigation of the behavior of pneumatic tires operating in soft soils, using failure theories of classical soil mechanics. A series of powered-wheel, programmed-slip performance tests conducted in sand and clay were analyzed. The soil in contact with the tire is considered to be in a state of failure at all slips, and it is hypothesized that the characteristic shape of the pull-slip curve is not due to the increase in soil deformation, but to the rotation of the failure plane with respect to the tire-soil interface. Using some simple assumptions and the approximation that measured forces were uniformly distributed over the tire-soil contact surface, it is demonstrated that the hypothesis is a plausible one. A key element in the analysis is the determination of an angle theta that represents the angle of the tire contact surface relative to the horizontal. Using this angle and the forces measured in a test, a relation between the ratio of tangential and normal stresses and slip was developed. This relation is interpreted as a measure of the rotation of the failure plane. There appears to be a linear relation between theta and slip in sand, and a hyperbolic relation in clay. A discussion of slip is included as Appendix A. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The study reported herein had a dual purpose. First, it was intended to determine, for certain specific circumstances, a mathematical relation between the various pertinent tire and soil parameters and the parameters that describe the behavior of the pneumatic tire-soil system. In particular it was desired to identify the role played by the soil in terms of relatively simple measures of the pertinent soil properties. A second purpose was to demonstrate the applicability and usefulness of dimensional analysis in experimental studies of a tire-soil system. 9.
