This book discusses efforts to control the low-frequency vibration transmission of typical power equipment and pipeline systems of ships, exploring the use of active and passive hybrid vibration isolation and adjustable dynamic vibration absorption technologies. It also proposes an adaptive feed-forward control strategy and studies a distributed feed-forward control hardware system. In addition, the book presents a three-way dynamic vibration absorption theory used to design a pipeline-system adjustable dynamic vibration absorber, which offers a number of advantages, such as compact structure, easy assembly and disassembly, low power consumption, excellent vibration control effect and wide frequency band adjustable ability, etc. This book is a valuable resource for researchers and engineers in the fields of noise and vibration control, active control systems, active vibration isolation and adaptive dynamic vibration absorption.

Demonstrates how to design active-passive vibration isolators Helps readers design and implement their own active vibration control systems Explains how to control low frequency vibration from an active control angle

Dr. Fei WANG majored in active noise and vibration control of merchant ships, vessels and warships. He has co-published 4 books, 13 papers and has registered 5 patents. Prof. Lin He is a Professor and Academic at the Chinese Academy of Engineering. He is a Ph.D. Supervisor, and a director of the Institute of Vibration and Noise Research, which since 2005 has developed the first generation of ship noise monitoring system in China, laying the foundation for the acoustic-characteristics management of ships. These developments have been widely used and have been granted a number of national invention patents. In recent years, his team has focused on "active and passive hybrid vibration isolation technology," achieving significant advances in a number of key areas. The series of anti-high pressure balanced flexible hoses he developed have outstanding pipeline vibration isolation properties, and have solved a number of noise reduction problems, and won the 2009 National Science and Technology Progress Award. He has written more than 50 papers and has co-published 4 academic monographs. Prof. Zhenping WENG is the Director of the Wuhan Second Ship Design and Research Institute, and the Director of the National Key Laboratory for Vibration and Noise of Defence Ships. His research interests include automatic control, intelligent control and noise and vibration control for ships. He has written more than 18 papers and has co-published 4 books.
