This book was released on 1974 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two single aircraft tires (20-20, 22-PR and 49-17, 26-PR) and three standard military trucks were tested under towed (nonpowered, nonbraked) and self-powered conditions, respectively, in buckshot clay test beds whose strengths ranged from about 110 to 600 cone index. Tests included multiple passes over the prepared test beds (usually 100 passes for the aircraft tires, 10 for the trucks) at low speeds. Only single-wheel configurations were examined (i.e., outer second- and third-axle wheels of the M35A2 and M51 were removed). Curves were developed to allow soil strength (airfield index) to be estimated directly from the rut produced by single or multiple passes of any of the three trucks. These curves were developed through use of a dimensionless prediction term (tire-clay numeric Nc) that allows pneumatic tire performance to be scaled over a wide range of soil strengths, wheel loads, and tire size, shape, and deflection conditions.

This book was released on 1970 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report describes a method for rapidly determining the soil strength at forward-area airfields. Soil strength indications are determined by measuring rut depths created by traffic of standard military ground vehicles. Initially, an office study was conducted that established the potential of such a method. Then limited field verification tests were conducted with four standard military ground vehicles operated on a prepared unsurfaced heavy clay subgrade. First-pass rut depths were measured for each vehicle operated empty and with maximum cross-country loading. The results of this testing indicated the feasibility of predicting soil strength based on one-pass rut depth caused by military ground vehicles. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: THEORY OF GROUND VEHICLES A leading and authoritative text for advancing ground vehicle mobility Theory of Ground Vehicles, Fifth Edition presents updated and expanded coverage of the critical factors affecting the performance, handling, and ride essential to the development and design of road and off-road vehicles. Replacing internal combustion engines with zero-emission powerplants in ground vehicles to eliminate greenhouse gas emissions for curbing climate change has received worldwide attention by both the vehicle industry and governmental agencies. To enhance safety, traffic flow, and operating efficiency of road transport, automated driving systems have been under active development. With growing interest in the exploration of the Moon, Mars, and beyond, research in terramechanics for guiding the development of extraterrestrial rovers has been intensified. In this new edition, these and other topics of interest in the field of ground vehicle technology are explored, and technical data are updated. New features of this edition include: Expanded coverage of the fundamentals of electric drives, hybrid electric drives, and fuel cell technology Introduction to the classification and operating principles of the automated driving system and cooperative driving automation Applications of terramechanics to guiding the development of extraterrestrial rovers Elaboration on the approach to achieving the optimal operating efficiency of all-wheel drive off-road vehicles Introduction to updated ISO Standards for evaluating vehicle ride An updated and comprehensive text and reference for both the educational and professional communities, Theory of Ground Vehicles, Fifth Edition will prove invaluable to aspiring and practicing engineers seeking to solve real-world road and off-road vehicle mobility problems.
