System Dynamics and Mechanical Vibrations: An Introduction / Edition 1

by Dietmar Findeisen

Overview

The Aim of the Book. This book is concerned with the subjects of vibrations and system dynamics on an integrated basis. Design engineers find themselves confronted with demands made on machin­ ery, structures and dynamic systems which are increasing at such a rate that dy­ namic performance requirements are always rising. Hence, advances in analysis and design techniques have to keep pace with recent developments in strong lightweight materials, more extensive knowledge of materials properties and structural loading. Whereas the excitation applied to structures is always increasing, the machine mass and damping is reduced. Consequently, unwanted vibra­ tions can have very serious effects on dynamic systems. It is, therefore, essential to carry out vibration analysis as an inherent part of machine design. The problems arising either from the observed or predicted dynamic behaviour of systems are of particular interest in control theory. Vibration theory places emphasis on analysis, which implies determining the response to given excitations, and any design amounts to changing the system parameters so as to bring about a satisfactory response. The improvement in performance achieved by changing solely the parameters of the mechanical system is very limited. How­ ever, a new approach to system design has proved to be more successful. It con­ sists of designing forces that, when exerted on the system, produce a satisfactory response. This approach, known as control, has become a ubiquitous part of the engineering curriculum, completing the conventional mechanical disciplines.

Editorial Reviews

Aus den Rezensionen: “... Eine wichtige Grundlage für mechatronische Systeme ist die Systemdynamik. Mit ihr kann das dynamische Verhalten des Gesamtsystems mit allen Komponenten untersucht werden ... In dem bereits im Jahr 2000 erschienenen Buch ... wird diese Grundlage in ausführlicher Form dargestellt. Das Buch richtet sich sowohl an Studenten als auch an Ingenieure der Praxis, die reale Probleme der Systemdynamik und der mechanischen Schwingungen bei der Entwicklung und Konstruktion von Maschinen und mechatronischen Systemen zu lösen haben ...“ (R. Nordmann, in: Konstruktion, 2010, Issue 4, S. 74)
