Download or read book Mechanics of Wheels on Soft Soils Report 2 Effect of Width on Rigid Wheel Performance written by E. M. Leflaive and published by . This book was released on 1967 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were run in an air-dried sand using three rigid wheels 28 in. in diameter and 12, 6, and 3 in. wide to determine the effect of wheel width on performance. Performance in the study was evaluated in terms of pull, torque, and dissipated energy. It was found that the width/diameter ratio influenced the rate of increase of torque energy at low slips, but at high slips, the slopes of the dissipated energy lines were approximately the same for all rigid wheels. An increase in load at a given high slip caused some changes in torque energy, and there was a load for which the torque energy was a minimum. The dissipated energy tended to increase with an increase in load, so the pull energy tended to decrease with an increase in load. Energy parameters measured in these tests with rigid wheels were compared with similar parameters from tests with pneumatic tires. In all cases, the pneumatic tire was found to be more efficient, with the better performance attributed mostly to a lower energy dissipation. (Author).

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.

Book excerpt: The report presents a method for studying the results of tests with wheels in soils. The first part emphasizes the need for a framework to describe observed facts, and in the next part, a method is developed to provide this framework. The method considers the work of the pull developed by the test wheel as the difference between energy input and energy dissipation. The parameters used to represent these energies are explained relative to the theoretical case of a rigid wheel on a hard surface. This reference condition also is used to distinguish the particular features of rolling motion on deformable soils. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Compared with forces occurring in soil mechanics problems in civil engineering, the forces that are applied to soil in farming operations generally have a short duration, less than a few seconds, a small loaded area, no more than a few square decimeters, and small intensities, 10 bar being a high value. On the other hand, soil properties vary widely between those of a weak mud and a stone-like dry soil. Tillage and related applications of force to soil are practiced worldwide in farming. Tillage operations are performed on one hectare of land for every three human beings. This means that for the food production for each individual daily, something like one cubic meter of soil is stirred, or about 20 times his body weight. Theoretical knowledge of this most common human activity, which largely determines the surface shape of the fertile part of the earth, is still very limited. In this book the authors have tried to give an outline of the present state of the art. One of the starting points was a course in soil dynamics taught by the authors at the Agricultural University at Wageningen, The Netherlands. We hope to reach interested readers who have no more theoretical knowledge than high school level, as well as readers who want to go beyond the level of a third year university student. For the chapter on wheels and tires we received substantial support from F. G. J. Tijink of the Tillage Laboratory at Wageningen.

Download or read book Vehicle Traction Mechanics written by R.N. Yong and published by Elsevier. This book was released on 2012-12-02 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fundamental problem in the study of vehicle mobility is the development of traction between the vehicle and the supporting terrain. The mechanics of energy transfer will essentially control the final performance of the surficial machine. Determining and predicting the capability of a particular piece of machinery to traverse successfully a specific piece of terrain is very complex, particularly as the characteristics and properties of different types of terrain cover vary considerably, as do the many types of vehicle and their running gear.The material that forms the basis of this book has been gathered over many years of study both in the laboratory and in the field. It studies vehicle traction mechanics from the viewpoint of the interaction between the vehicle and the ground surface. The types of machines covered include earth-moving, forestry, agricultural, and construction machines. In addition, the mechanisms involved in the development of traction and the working of the terrain through cultivation, construction and surface disturbances are examined. The book also addresses the problems of off-road mobility and terrain trafficability, especially from the terrain-support and terrain interaction points of view. It is the authors' aim that the book will provide the reader with the ability to both analyze and predict the traction capability of his proposed machinery, and also to anticipate the kinds of reactions that will occur in the ground and at the ground surface.
