Nonlinear Targeted Energy Transfer in Mechanical and Structural Systems (eBook, PDF)

• Format: PDF

Produktbeschreibung

This monograph is the first in the new area of targeted nonlinear energy transfer in mechanical and structural systems. This concept was initially discovered by the two leading authors in 1999, and was further developed exclusively by the entire author group in the last 6 years. Since then, additional groups of researchers in the USA, Russia, UK and France have started working on this concept and applying it. It is estimated that in the years to come, the concept of targeted nonlinear energy transfer will be considered and applied by numerous groups ofresearchers and practitioners internationally. This monograph presents theoretical methods, computational results and experimental demonstrations of this concept applied to discrete and continuous coupled nonlinear oscillators. Moreover, it demonstrates the wide applicability of targeted nonlinear energy transfer to a wide range of problems, including: - Vibration and shock isolation in mechanical systems - Seismic mitigation - Aeroelastic and structural instability suppression - Drilling operations - Packaging devices This is a groundbreaking and unique volume, providing new design paradigms in a variety of fields.

Rezensionen

From the reviews:

"Two volumes of this monograph present an original approach to the problems of passive vibration control of dissipative mechanical and structural systems subjected to broadband transient inputs, including topics of targeted energy transfer (TET) and nonlinear energy sink (NES). ... This monograph is intended for scientists and mechanical and civil engineers who have a general knowledge of analytical dynamics and ordinary and partial differential equations, as well as integro-differential equations." (Jerzy Gawinecki, Zentralblatt MATH, Vol. 1170, 2009)

"This two-volume monograph addresses the problem of passive vibration control of mechanical systems in which a strongly nonlinear, passive, local attachment is used as a damper. The aim is to provide an in-depth explanation of the analytical, computational, and experimental techniques required to study targeted energy transfer. The applicability of the techniques to a wide range of areas is demonstrated. The intended audience is researchers and engineers interested in one-way energy transfer." (IEEE Control Systems Magazine, Vol. 30, April, 2010)
