This book provides a comprehensive coverage of vehicle system dynamics and control, particularly in the area of integrated vehicle dynamics control. The book consists of two parts, (1) development of individual vehicle system dynamic model and control methodology; and (2) development of integrated vehicle dynamic model and control methodology. The first part focuses on investigating vehicle system dynamics and control according to the three directions of vehicle motions, including longitudinal, vertical, and lateral. Corresponding individual control systems, e.g. Anti-lock Brake System (ABS), Active Suspension, Electric Power Steering System (EPS), are introduced and developed respectively.
Particular attention is paid in the second part of the book to develop integrated vehicle dynamic control system. Integrated vehicle dynamics control system is an advanced system that coordinates all the chassis control systems and components to improve the overall vehicle performance including safety, comfort, and economy. Integrated vehicle dynamics control has been an important research topic in the area of vehicle dynamics and control over the past two decades. The research topic on integrated vehicle dynamics control is investigated comprehensively and intensively in the book through both theoretical analysis and experimental study. In this part, two types of control architectures, i.e. centralized and multi-layer, have been developed and compared to demonstrate their advantages and disadvantages.

Some gear-tooth working-surface manufacturing deviations of significant amplitude cause negligible vibration excitation and noise, yet others of minuscule amplitude are a source of significant vibration excitation and noise. Presently available computer-numerically-controlled dedicated gear metrology equipment can measure such error patterns on a gear in a few hours in sufficient detail to enable accurate computation and diagnosis of the resultant transmission-error vibration excitation. How to efficiently measure such working-surface deviations, compute from these measurements the resultant transmission-error vibration excitation, and diagnose the manufacturing source of the deviations, is the subject of this book.
Use of the technology in this book will allow quality spot checks to be made on gears being manufactured in a production run, to avoid undesirable vibration or noise excitation by the manufactured gears. Furthermore, those working in academia and industry needing a full mathematical understanding of the relationships between tooth working-surface deviations and the vibration excitations caused by these deviations will find the book indispensable for applications pertaining to both gear-quality and gear-health monitoring.
Key features:Provides a very efficient method for measuring parallel-axis helical or spur gears in sufficient detail to enable accurate computation of transmission-error contributions from working-surface deviations, and algorithms required to carry out these computations, including examples Provides algorithms for computing the working-surface deviations causing any user-identified tone, such as ‘ghost tones,’ or ‘sidebands’ of the tooth-meshing harmonics, enabling diagnosis of their manufacturing causes, including examples Provides explanations of all harmonics observed in gear-caused vibration and noise spectra. Enables generation of three-dimensional displays and detailed numerical descriptions of all measured and computed working-surface deviations, including examples

In an accessible and timely work of scholarship, celebrated historian Joshua B. Freeman tells the story of the factory and examines how it has reflected both our dreams and our nightmares of industrialization and social change. He whisks readers from the early textile mills that powered the Industrial Revolution to the factory towns of New England to today’s behemoths making sneakers, toys, and cellphones in China and Vietnam. Behemoth offers a piercing perspective on how factories have shaped our societies and the challenges we face now.
Thoroughly revised and expanded with hundreds of pages of new material to reflect changes in the 2011 NEC, McGraw-Hill’s National Electrical Code 2011 Handbook, 27th Edition provides authoritative guidance and analysis to help you accurately interpret 2011 NEC rules. Co-author and working electrician, Frederic P. Hartwell, who has participated in the NEC process for almost thirty years, describes problems and difficulties in NEC provisions from an unbiased and practical perspective.
