Book Description
The increase in levels of sophistication and complexity of modern passenger cars and commercial vehicles is being driven by environmental requirements. Braking systems can no longer be considered in isolation - the interactions between vehicle braking, steering, handling, etc., particularly in emergency conditions, are leading to the development of adaptive integrated vehicle control systems. Building upon the success of previous volumes in the series, Braking 2004-Vehicle Braking and Chassis Control reflects the interaction of braking with the whole vehicle. Road vehicle braking behaviour experts, both from academia and industry, present the latest research and development devoted and applied to all aspects of braking, and report on field experiences with modern sophisticated systems. Braking 2004 is essential reading for engineers and researchers from across a wide range of disciplines, from highway engineers and tyre specialists to experts in intelligent control systems, and including, of course the traditional foundation - brake specialists.

Book Description
Acoustics is the science concerned with the production, control, transmission, reception, and effects of sound. Its origins began with the study of mechanical vibrations and the radiation of these vibrations through mechanical waves, and still continue today. Research was done to look into the many aspects of the fundamental physical processes involved in waves and sound and into possible applications of these processes in modern life. The study of sound waves also leads to physical principles that can be applied to the study of all waves. The broad scope of acoustics as an area of interest and endeavour can be ascribed to a variety of reasons. First, there is the ubiquitous nature of mechanical radiation, generated by natural causes and by human activity. Then, there is the existence of the sensation of hearing, of the human vocal ability, of communication via sound, along with the variety of psychological influences sound has on those who hear it. Such areas as speech, music, sound recording and reproduction.

Book Description
This book studies methods for a robust design of rotors against self-excited vibrations. The occurrence of self-excited vibrations in engineering applications if often unwanted and in many cases difficult to model. Thinking of complex systems such as machines with many components and mechanical contacts, it is important to have guidelines for design so that the functionality is robust against small imperfections. This book discusses the question on how to design a structure such that unwanted self-excited vibrations do not occur. It shows theoretically and practically that the old design rule to avoid multiple eigenvalues points toward the right direction and have optimized structures accordingly. This extends results for the well-known flutter problem in which equations of motion with constant coefficients occur to the case of a linear conservative system with arbitrary time periodic perturbations.

Book Description
The objectives of this third edition of an SAE classic title are to provide readers with the basic theoretical fundamentals and analytical tools necessary to design braking systems for passenger vehicles and trucks that comply with safety standards, minimize consumer complaints, and perform safely and efficiently before and while electronic brake controls become active. This book, written for students, engineers, forensic experts, and brake technicians, provides readers with theoretical knowledge of braking physics, and offers numerous illustrations and equations that make the information easy to understand and apply. New to this edition are expanded chapters on: • Thermal analysis of automotive brakes • Analysis of hydraulic brake systems • Single vehicle braking dynamics

Book Description
Inhaltsangabe:Abstract: This thesis presents a control algorithm for semi-active suspensions to reduce the braking distance of passenger cars. Active shock absorbers are controlled and used to influence the vertical dynamics during ABS-controlled full braking. In today s series cars the active shock absorbers are switched to a passive damping - usually hard damping - during ABS-braking. Several approaches to reduce oscillations of vertical dynamic tire forces are known, implemented and some of them tested in non-braking situations (refer to Yi, Valà ek, and Nouillant). The approach presented in this paper goes a step further by connecting the vertical with the longitudinal dynamics. To influence the vertical dynamics a switching control logic, called MiniMax-controller, is used. It is named after the fact that it changes only from soft to hard damping and vice versa. A control quantity was identified that connects the vertical dynamics with the longitudinal dynamics: the integral of dynamic wheel load. The control algorithm is implemented in a compact class passenger car. Simulations with a quarter-car model have been undertaken as well as tests on a 4-post-test rig, driving tests with defined excitations (like defined obstacles), and test drives on a real road, using a braking machine for reproducibility reasons. It could be shown that it is possible to reduce the braking distance by affecting on the vertical dynamics of a passenger car in general. The amount of reduction depends on the elevation profile of the chosen testing track and on the initial velocity. On a road with an unevenness comparable to the one that is found on a typical German Autobahn, a reduction of typically 1-2%, compared to the best passive damping, was achieved.
