For years, engineers have turned to Aerodynamics of Road Vehicles as their 'bible' on this field. The fourth edition continues this tradition. Much of the material has been substantially revised, and new chapters on wind noise and motorcycles have been added. Aerodynamics of Road Vehicles thoroughly covers the fundamental principles that influence vehicle performance, handling, safety and comfort.

An excellent introduction to the topic for the novice or student and a useful refresher and reference for the expert, the book focuses on:

  • The fundamentals of fluid dynamics as related to vehicle aerodynamics
  • Specific experimental results
  • Design strategies, showing how existing individual results can be applied to specific problems
  • Development techniques, as related to different types of wind tunnels, on-road tests and numerical methods.

The aerodynamics of passenger cars, commercial vehicles, sports and race cars, and motorcycles are dealt with in detail. Related fields that are influenced by aerodynamics are also covered, including the effects of aerodynamics on fuel economy, directional stability, engine cooling, and passenger comfort.

Contents include:

  • Introduction to Automobile Aerodynamics (including a section on its history)
  • Some Fundamentals of Fluid Mechanics
  • Performance of Cars and Light Trucks
  • Aerodynamics Drag of Passenger Cars
  • Directional Stability
  • Function, Safety, and Comfort

It is our pleasure to present these proceedings for “The Aerodynamics of Heavy Vehicles II: Trucks, Buses and Trains” International Conference held in Lake - hoe, California, August 26-31, 2007 by Engineering Conferences International (ECI). Brought together were the world’s leading scientists and engineers from industry, universities, and research laboratories, including truck and high-speed train manufacturers and operators. All were gathered to discuss computer simu- tion and experimental techniques to be applied for the design of the more efficient trucks, buses and high-speed trains required in future years. This was the second conference in the series. The focus of the first conference in 2002 was the interplay between computations and experiment in minimizing ae- dynamic drag. The present proceedings, from the 2007 conference, address the development and application of advanced aerodynamic simulation and experim- tal methods for state-of-the-art analysis and design, as well as the development of new ideas and trends holding promise for the coming 10-year time span. Also - cluded, are studies of heavy vehicle aerodynamic tractor and trailer add-on - vices, studies of schemes to delay undesirable flow separation, and studies of - derhood thermal management.

Concern about the reduced availability and the increased cost of petroleum fuels prompted great efforts in recent years to reduce the fuel consumption of auto mobiles. The ongoing efforts to reduce fuel consumption have addressed many relevant factors, including increased engine performance, reduced friction, use of lightweight materials, and reduced aerodynamic drag. The results of the investigations assessing the various factors affecting fuel economy have been published in journals, conference proceedings, and in company and government reports. This proliferation of technical information makes it difficult for workers to keep abreast of aU developments. The material presented in this book brings together in a single volume much of the relevant materials, summarizes many of the state-of-the-art theories and data, and provides extensive lists of references. Thus, it is hoped that this book will be a useful reference for specialists and practicing engineers interested in the fuel economy of automobiles. J. C. HILLIARD o. S. SPRINGER vii CONTENTS 1.

'An Introduction to Modern Vehicle Design' provides a thorough introduction to the many aspects of passenger car design in one volume. Starting with basic principles, the author builds up analysis procedures for all major aspects of vehicle and component design. Subjects of current interest to the motor industry, such as failure prevention, designing with modern materials, ergonomics and control systems are covered in detail, and the author concludes with a discussion on the future trends in automobile design. With contributions from both academics lecturing in motor vehicle engineering and those working in the industry, "An Introduction to Modern Vehicle Design" provides students with an excellent overview and background in the design of vehicles before they move on to specialised areas. Filling the niche between the more descriptive low level books and books which focus on specific areas of the design process, this unique volume is essential for all students of automotive engineering. Only book to cover the broad range of topics for automobile design and analysis procedures Each topic written by an expert with many years experience of the automotive industry

These Proceedings contain the papers and oral discussions presented at the Symposium on AERODYNAMIC DRAG MECHANISMS of Bluff Bodies and Road Vehides held at the General Motors Research Laboratories in Warren, Michigan, on September 27 and 28, 1976. This international, invitational Symposium was the twentieth in an annual series, each one having been in a different technical discipline. The Symposia provide a forum for areas of science and technology that are of timely interest to the Research Laboratories as weIl as the technical community at large, and in which personnel of the Laboratories are actively involved. The Symposia furnish an opportunity for the exchange of ideas and current knowledge between participating research specialists from educational, industrial arid governmental institutions and serve to stimulate future research activity. The present world-wide energy situation makes it highly desirable to reduce the force required to move road vehicles through the atmosphere. A significant amount of the total energy consumed for transportation is expended in overcoming the aerodynamic resistance to motion of these vehicles. Reductions in this aerodynamic drag can therefore have a large impact on ground transportation energy requirements. Although aerodynamic development work on road vehides has been performed for many years, it has not been widely reported or accompanied by much basic research.

Leistung, Fahrverhalten und Komfort eines Automobils werden nachhaltig von seinen aerodynamischen Eigenschaften bestimmt. Ein niedriger Luftwiderstand ist die Voraussetzung dafür, dass die hochgesteckten Verbrauchziele erreicht werden. Die Aerodynamik des Automobils ist 1981 erstmalig erschienen und seitdem zu einem Standardwerk geworden. Der Stoff ist von Praktikern erarbeitet worden, die aus einer Vielzahl von Versuchen strömungsmechanische Zusammenhänge ableiten und Strategien beschreiben.Bei unveränderter Geamtkonzeption wurden für die 6. Auflage neue Ergebnisse zum induzierten Widerstand und zur Haltung der Fahrtrichtung bei Seitenwind aktualisiert. Völlig neu wurden die Kapitel über Kühlung und Durchströmung(HVAC) sowie über numerische Methoden wie CFD, Netzgenerierung und CAD erarbeitet.

This work serves as a reference concerning the automotive chassis, i.e. everything that is inside a vehicle except the engine and the body. It is the result of a decade of work mostly done by the FIAT group, who supplied material, together with other automotive companies, and sponsored the work. The first volume deals with the design of automotive components and the second volume treats the various aspects of the design of a vehicle as a system.

Die aerodynamische Gestaltung von Brücken, Hochhäusern, Zügen und Bahnen oder Kraftfahrzeugen ist äußerst schwierig. Ihre Umströmung wird - typisch für stumpfe Körper - von Ablösungen geprägt und deren Verhalten lässt sich nur mit großem Aufwand voraussagen. Lange Zeit erfolgte das ausschließlich experimentell; zunehmend kommen nun aber auch numerische Verfahren zum Einsatz. In jedem Fall erfolgt die Optimierung all dieser Körper nach dem Prinzip von Versuch und Irrtum. Will man dabei schnell zum Ziel kommen, dann erweist es sich als nützlich, das vorliegende Problem auf einen möglichst einfachen Modellfall zurückzuführen. Die Gesetzmäßigkeiten der Umströmung geometrisch so einfacher Körper wie Kreiszylinder und Kugel, Keil und Kegel sowie Quader sind eingehend erforscht worden. Mit Umsicht lassen sie sich auf komplexere Formen übertragen. Das Buch stellt die dazu erforderlichen Grundlagen bereit.
