This book extends the focus to all the entities that participate in the successful quest for safety and demonstrates how Design, Manufacturing, Maintenance, (inspection), Operation, Requirements, (regulations) all are part of successful, safe innovation, and necessary to assure Safe flight thru the life of the vehicle. It addresses the notion that safety is a function of time and a vigilant risk management is only successful, if it includes all participating entities.
It is a companion to the author's first volume Composite Structure: Design, Safety and Innovation, published by Elsevier in June 2005.
The book
- eliminates an unacceptable 'gap' in the world of safety
- represents a 'new' approach to designing, manufacturing, maintaining, operating and regulating composite airplane structures
- for professionals in the aerospace structural development arena whether in indusrty, academia or government
The recommendations by the White House Commission on Aviation Safety and Security resulted in requirements of safety measures that are both objective and performance-driven,
This book was created to put in place the philosophy and foundation that identifies all the Elements of Safety that contribute to the Probability of an Unsafe State. The case-by-case influence of the variability of Processes and the detail geometry level. The effects on structural criticality and integrity by Material Types, Manufacturing Concepts and Structural Concepts

Vibration Control of Active Structures: An Introduction

Vibration Control of Active Structures: An Introduction
A. Preumont,
Springer
2002
ISBN: 1402004966
385 pages
PDF 12,1 MB
This text is an introduction to the dynamics of active structures and to the feedback control of lightly damped flexible structures; the emphasis is placed on basic issues and simple control strategies that work. This book consists of 14 chapters. Chapters 2 and 3 are devoted to the dynamics of active structures; the open loop transfer functions are derived from the constitutive equations; the discussion includes active trusses with piezoelectric struts, and beams and shells with embedded laminar piezoelectric actuators and sensors. Chapters 4 and 5 discuss the virtues of collocated actuator/sensor configurations and how they can be exploited to develop active damping with guaranteed stability. Chapter 6 addresses vibration isolation for one and 6 d.o.f.. Chapter 7 discusses optimal control for SISO systems with symmetric root locus. Chapter 8 discusses the design tradeoffs for SISO systems in the frequency domain, including the Bode amplitude/phase relationship. Chapter 9 provides a more general discussion of optimal control using of optimal control using the Riccati equation; spillover is examined. Chapters 10 and 11 review briefly the concepts of controllability, observability and stability. Chapter 12 discusses the semi-active control, including some materials on magneto-rheological fluids. Chapter 13 describes various practical applications to active damping, precision positioning and vibroacoustics, and chapter 14 discusses the active damping of cable- structures. This book is intended for structural engineers who want to acquire some background in vibration control; it can be used as a textbook for a graduate course on vibration control or active structures. The text is supplemented with 113 problems; a solutions manual is available through the publisher to teachers using this book as a textbook.
