Heavy-duty wheeled vehicles (HDWVs) are all-wheel-drive vehicles that carry 25 tons or more and have three or more axles. They transport heavy, bulky cargo such as raw minerals, timber, construction materials, pre-fabricated modules, weapons, combat vehicles, and more. HDWVs are used in a variety of industries (mining, logging, construction, energy) and are critical to a country’s economy and defense. These vehicles have unique development requirements due to their high loads, huge dimensions, and specific operating conditions. Hauling efficiencies can be improved by increasing vehicle load capacity; however capacities are influenced by legislation, road limits, and design. Designing HDWVs differs from other multi-purpose all-wheel-drive vehicles. The chassis must be custom-designed to suit the customer’s particular purpose. The number of axles is another variable, as well as which ones are driving and which are driven. Tires are also customizable.
This second edition of The Shock Absorber Handbook (first edition published in 1999) remains the only English-language book devoted to the subject. Comprehensive coverage of design, testing, installation, and use of the damper has led to the book's acceptance as the authoritative text on the automotive applications of shock absorbers. In this edition, the author presents a thorough revision of his book, bringing it completely up to date. There are numerous detail improvements, and extensive new material has been added, particularly on the many varieties of valve design in the conventional hydraulic damper, and on modern developments such as electrorheological and magnetorheological dampers. The text is generously illustrated throughout with numerous diagrams and photographs.

Hand-selected by racing engineer legend Carroll Smith, the 28 SAE Technical Papers in this book focus on the chassis and suspension design of pure racing cars, an area that has traditionally been - farmed out - to independent designers or firms since the early 1970s. Smith believed that any discussion of vehicle dynamics must begin with a basic understanding of the pneumatic tire, the focus of the first chapter. The racing tire connects the racing car to the track surface by only the footprints of its four tires. Through the tires, the driver receives most of the sensory information needed to maintain or regain control of the race car at high force levels. The second chapter, focusing on suspension design, is an introduction to this complex and fascinating subject. Topics covered include chassis stiffness and flexibility, suspension tuning on the cornering of a Winston Cup race car, suspension kinematics, and vehicle dynamics of road racing cars.
Through appendices and diagrams, Car Suspension and Handling, 4th Edition outlines the purpose and history of vehicle suspension systems, while defining the basic parameters of suspension geometry. In addition, the book delves into human sensitivity to vibration, and offers data on durability, tire background information, steering calculations and suspension calculations.
This editorial review of J784a is based upon decades of experience in the practical application of x-ray diffraction residual stress measurement methods in thousands of individual applications. J784 is a classic document. It serves as the only recognized standard for residual stress measurement available. The purpose of this revision is not to incorporate all of the research in the fields of x-ray and neutron diffraction but to focus on the practical applications of x-ray diffraction techniques useful to members of the automotive engineering related industries.
Riding on Air covers the history of air suspension, from the earliest patents in the mid-19th century to more current developments. Beginning on buses, air suspension expanded into passenger rail vehicles, only to be followed by a crashing failure on passenger cars. But after several precarious years, air suspension began to win almost universal acceptance on trucks and trailers, and then in mass transportation, eventually making a successful return to passenger cars.
This book provides comprehensive coverage of the design, installation and use of the shock absorber. Among the subjects highlighted are fluid dynamics, valve characteristics, damper characteristics, installation and motion ratios, and influence on vehicle ride and handling. Numerous example installations are described and discussed. Testing machines, as well as methods of laboratory testing, are also described in detail. The widely varying characteristics of variable dampers, and the relationship to their design features, are explained.
A detailed design manual on all aspects of helical and spiral springs, this publication covers: spring materials, cold-wound helical and spiral springs; hot-coiled helical springs; and design of helical springs.
This book provides detailed coverage of the theory and practice of vehicle cornering and handling. Much of the material in this book is not available elsewhere, including unique information on suspension analysis, understeer/oversteer, bump steer and roll steer, roll centers, limit handling, and aerodynamics. Each chapter ends with a wide selection of problems, providing an ideal review. This book is an excellent resource for vehicle designers and engineering students who want to better understand and analyze the numerous factors affecting vehicle handling.
The extensive and increasing use of pneumatic springs in automotive applications has made it appropriate that this manual be prepared to assist the engineer and the designer in understanding the basic principles and uses of pneumatic springs. This manual provides descriptions of the principles involved in pneumatic spring function along with details of the various configurations of pneumatic spring devices and the unique characteristics of each. Pneumatic spring types have been defined correlating with SAE J511 in the SAE (Oct. 1970) handbook regarding pneumatic spring terminology. Background information tracing the evolution of pneumatic springs has been included, as well as some specific examples of design calculations to serve as a guideline for the designer.
Written by David Cebon, Research Director of the Cambridge vehicle dynamics consortium, this award winning publication focuses on the interaction between heavy vehicles and roads. Organized into six sections, contents include: road response and damage; static loading considerations; dynamic tire forces; road damage due to dynamic tire forces; suspension assessment.
This manual is the latest edition in the group of spring manuals currently under the review of the SAE Spring Committee. The preceding SAE manuals on coned disk springs were published in 1950 (First edition), and 1955 (Second Edition). Developments during the past 30 years necessitated a complete revision. In addition to updating the treatment of coned Disk springs, material on other spring washers, not directly related to the coned Disk Spring, has been added. In accordance with current sAE practice, customary units have been replaced by metric SI units throughout this manual; for a conversion table see the Appendix.
This manual is written as a guide for the designer of leaf spring installations. It contains information which will make it possible to calculate the space required for a leaf spring, to provide suitable attachments, and to determine the elastic and geometric properties of the assembly. The detail design of the spring itself also is described, but it was not the intention of the Committee to lay down fixed rules for this. The choice of leaf lengths, leaf thicknesses, and leaf curvatures depends upon the type of installation and upon the kind of service. Only an experienced spring engineer can make the best choice of these factors. It is therefore recommended that the designer of a leaf spring installation consult a spring maker before the design is finalized.
