2. Content introduction
The basic goal of this textbook is to provide a basic knowledge of road vehicle dynamics and to impart modeling insights and details. Road vehicles have been developed and manufactured for over 125 years. From the beginning until now, the main goal of vehicle dynamics has been to achieve optimal safety and ride comfort. Today, computer simulation has become an important tool for developing new and enhancing existing road vehicle concepts. Electronic control components offer new options. Typically, they are developed and tested in a software-in-the-loop (SIL) or hardware-in-the-loop (HIL) environment. Today, automotive engineers need basic fundamental knowledge and skills to build basic simulation models, handle complex models, or operate simulation tools correctly. However, currently only books on the basics or modeling of vehicle dynamics are available. This textbook combines these two courses together for the first time. A first dynamics course and basic knowledge of programming languages are prerequisites.
The lecture notes from the undergraduate course Vehicle Dynamics form the basis of this textbook. These notes were subsequently expanded as the basis for a postgraduate course, first taught by the author in 1992 at the State University of Campinas and repeated many times since as a short course in vehicle dynamics. Part of the instructions, combined with other material, were also used in internal workshops at different automotive suppliers, as well as in several workshops at conferences on different topics in vehicle dynamics. A truly inspiring and personal encounter with Vladimir V. Vantsevich, editor of the Ground Vehicle Engineering series, at the 21st International Symposium on Road and Rail Vehicle Dynamics in 2009 culminated in a proposal to Chapman & Hall/CRC A textbook proposal. Class lecture notes and seminar materials formed the skeleton of the first edition of this textbook.
The second edition retains the basic structure of the textbook and provides additional topics, examples, and exercises. The number of pages has only increased slightly, as the page layout has been slightly expanded.
Now, symbols have been adjusted as common symbols in vehicle dynamics. The newly added section explains the main meaning of the symbols. In addition, a short glossary at the end of the textbook explains typical phrases in vehicle dynamics.
Exercises at the end of each chapter are used to repeat material and check the reader's knowledge. Many programming examples integrated into this textbook, available for download on the publisher's website, deepen the understanding of vehicle dynamics and make serious self-study possible. MATLAB® is used as a programming language due to its ease of use and popularity.
This textbook can be used for classroom teaching and self-study in vehicle dynamics graduate courses. Skipping the modeling aspect, it would be suitable for an "Introduction to Vehicle Dynamics" course for upper-division undergraduate students. The modeling aspect can even be integrated into multibody dynamics courses. In addition, this text will help practicing engineers and scientists in the field of vehicle dynamics by providing a complete set of vehicle models that can be used for basic research, parameter variation, optimization, and simulation of different driving operations.
This textbook uses the modern International System of Units.
The introduction in Chapter 1 provides an overview of units and quantities, discusses terminology in vehicle dynamics, deals with definitions, provides an overview of multibody dynamics, and derives the equations of motion for the first vehicle model.
Chapter 2 specifically introduces this road. First, a complex road model is discussed, and then deterministic and stochastic road models are described in detail. The quarter car model with trailing arm suspension introduced in Chapter 1 is used to demonstrate the effects of rough roads on the wheels and chassis.
Chapter 3 discusses the TMeasy steering tire model. It includes complex contact calculations and provides all forces and torques. Longitudinal and transverse forces as well as torques about the vertical axis are modeled with first-order dynamics. Additionally, aspects of measurement techniques and modeling are discussed.
Chapter 4 mainly introduces the transmission system. First the components and concepts of the different power trains are discussed. Then, the dynamics of the wheels and tires were studied in detail. A simple wheel-tire model including a lockable braking torque model is proposed and studied through corresponding MATLAB simulations. A brief description of the layout and modeling aspects of differentials, standard drive trains, transmissions, clutches and different power sources completes the chapter.
Chapter 5 discusses the purpose and components of suspension systems. The dynamic model of rack and pinion steering and the kinematic model of double wishbone suspension system were established and analyzed through simulation results. The newly included design kinematics make it possible to model arbitrary suspension systems or match kinematics and compliance testing smoothly and efficiently. The design kinematics can even approximate a statically overdetermined suspension system in a quasi-static manner. This specific capability is demonstrated by a torsion beam suspension system, a cheap and robust solution for front-wheel drive car or semi-trailer axles. Chapter 5 ends with a typical racing suspension system model.
Chapter 6 is devoted to the discussion of force elements. Unrealistic air spring model added here. In addition to standard force-bearing elements such as springs, anti-roll bars and dampers, dynamic force-bearing elements including hydraulic mounts are also discussed in detail. Complex models of swept sinusoidal excitation are provided here, as well as models of different dynamic forces.
Chapters 7 to 9 provide the basic principles of vertical, longitudinal and transverse vehicle dynamics. Each chapter starts with a simple modeling approach. Then, the influence of nonlinear, dynamic and even active dynamic elements is studied, as well as the influence of suspension kinematics. Sections 7.2 and 7.7 have been completely revised and expanded. Practical aspects and applications complete the chapters. Chapter 8 contains a newly added flat vehicle model that demonstrates the basic principles of anti-lock braking systems. Section 9.4 discusses vehicles equipped with additional rear-wheel steering systems.
Finally, Chapter 10 presents the concept of a fully three-dimensional vehicle model and shows and discusses typical results from standard driving maneuvers. A new section describes the impact of mechatronic systems on vehicle dynamics.
The results of the exercises and all MATLAB examples as well as some additional M-files are available for download on the publisher's website. An executable MATLAB script is represented by a name of type app_no_name.m, where app represents the application, no refers to the number of the corresponding chapter in the textbook, and name specifies the specific topic. Most scripts refer to functions, which have names of the form fun_no_name.m or uty_name.m. The former refers to a specific function (fun), and the latter refers to a general utility function (uty). The other MATLAB script named xtra_no_name.m is not listed in the textbook. The MATLAB files available on the publisher's website represent a set of virtual test benches that can be used in courses or self-study. MATLAB applications can reflect and deepen understanding of different problems in vehicle dynamics by studying the impact of model parameters on results or by modifying simulation inputs.
The first author is very grateful to Vladimir V.Vantsevich, who encouraged him to write such a textbook. The authors also thank the publisher, Jonathan W, the senior editor. Plant and editorial assistant Bhavna Saxena are grateful for their support, which allows us to focus on content rather than worrying about layout. The former provided the necessary support for the first edition and initiated the second edition, while the latter was responsible for the administrative tasks of this textbook.
