Active and Passive Vibration Damping

Preface

This book is intended to present the basic principles and potential applications of passive and active vibration damping technologies. The presentation encompasses a mix between the associated physical fundamentals, governing theories, and optimal design strategies of various configurations of vibration damping treatments. Utilization of smart materials to augment the vibration damping of passive treatments is the common thread that is pursued, in depth, throughout the book.

The focus has been on developing a deeper understanding of the science behind various phenomena that govern the control of structural vibration using appropriate damping techniques. It is my intention, in writing this book, to explain in a simple yet comprehensive manner such scientific basics with particular focus on viscoelastic damping materials and the means for controlling passively and actively their energy dissipation characteristics. The book was developed throughout the years during my teaching of various classes on passive and active vibration and noise control. My research in these areas has enriched my teaching and broadened my understanding of these topics. I have tried to blend simple theory with basic engineering practice to enable the students and practicing engineers to understand the science and apply it with confidence. My guide in this effort has been the saying of Albert Einstein:

“Why does this applied science, which saves work and makes life easier, bring us so little ...
