Book excerpt: The report deals with one small phase of the problem of mobility for cross-country vehicles, namely a wheel being towed through soft soil. A new concept in soil mechanics is sought which will cope with the problem of the behavior of soil when massive displacements are involved, as occurs when a wheel cuts a deep rut in soft material. It is suggested that such movement of a soil is more in the nature of a flow phenomenon, and an energy-per-unit-volume concept is hypothesized in which the total energy spent (area under the load-sinkage curve) is divided by the net volume of soil displaced by a penetrating element.

Available in PDF, EPUB and Kindle. Book excerpt: An updated edition of the classic reference on the dynamics of road and off-road vehicles As we enter a new millennium, the vehicle industry faces greater challenges than ever before as it strives to meet the increasing demand for safer, environmentally friendlier, more energy efficient, and lower emissions products. Theory of Ground Vehicles, Third Edition gives aspiring and practicing engineers a fundamental understanding of the critical factors affecting the performance, handling, and ride essential to the development and design of ground vehicles that meet these requirements. As in previous editions, this book focuses on applying engineering principles to the analysis of vehicle behavior. A large number of practical examples and problems are included throughout to help readers bridge the gap between theory and practice. Covering a wide range of topics concerning the dynamics of road and off-road vehicles, this Third Edition is filled with up-to-date information, including: * The Magic Formula for characterizing pneumatic tire behavior from test data for vehicle handling simulations * Computer-aided methods for performance and design evaluation of off-road vehicles, based on the author's own research * Updated data on road vehicle transmissions and operating fuel economy * Fundamentals of road vehicle stability control * Optimization of the performance of four-wheel-drive off-road vehicles and experimental substantiation, based on the author's own investigations * A new theory on skid-steering of tracked vehicles, developed by the author.

Available in PDF, EPUB and Kindle. Book excerpt: The performance of single, pneumatic-tired, towed wheels operating in turned mode was investigated in a pilot study. Ninety-nine one-pass tests were conducted in the laboratory on one clay and two air-dry sands with 8.50-10, 7.00-6, and 6.00-9 tires. Turn angles were 0, 5, 10, 15, and 20 deg; wheel loads were varied from about 1000 to 7000 N; and tire deflections were 0.15, 0.25, 0.35, and 0.40 of the undeflected tire section heights. Clay consistencies ranged from soft to medium stiff, with corresponding one penetration resistances between 255 and 543 kPa. Relative densities of the sands ranged from medium dense to very dense, with corresponding cone penetration resistance gradients ranging from 0.7 to 4.6 MPa/m. Performance expressed in terms of towed force coefficient, side force coefficient, resultant coefficient, lateral force/drag, sinkage coefficient, and slip is influenced by the following independent variables: turn angle, soil strength, tire deflection, wheel load, and the product of tire width and diameter. Trail moment and eccentricity of the resultant are influenced more or less similarly. For the ranges of the variables tested, the U.S. Army Engineer Waterways Experiment Station system of dimensionless parameters for predicting performance of towed wheels operating at zero turn angle on clay and on sand is extended to treat turn angles larger than zero. For this purpose, turn angle and mobility numbers for sand and clay, combined with additional independent dimensionless variables, are correlated with the aforementioned six performance parameters.
