Book Description
Theoretical methods are presented for the analytic and experimental determination of mechanical impedance and its associated effects on the dynamic response of linear, multi-degree of freedom/multi-dimensional systems. Impedance matrices are formulated which are useful in describing and predicting the frequency dependent characteristic properties of these systems. The problem of interconnecting subsystems is formulated in terms of composite impedance matrices and interconnection equations, from which critical frequencies (resonances and anti-resonances) and dynamic response of the composite system may be obtained. Analytical and experimental procedures for the evaluation of these matrices are also discussed. To demonstrate the application of some of the procedures, an example problem is solved. Moreover, the results of this study are sufficiently general for extending the approach to many types of distributed system configurations subject to varied excitation phenomena.

Substructuring in Engineering Dynamics
Author: Matthew S. Allen
Publisher: Springer
ISBN: 3030255328
Category : Technology & Engineering
Languages : en
Pages : 277
Book Description
This book reviews the most common state-of-the art methods for substructuring and model reduction and presents a framework that encompasses most method, highlighting their similarities and differences. For example, popular methods such as Component Mode Synthesis, Hurty/Craig-Bampton, and the Rubin methods, which are popular within finite element software, are reviewed. Similarly, experimental-to-analytical substructuring methods such as impedance/frequency response based substructuring, modal substructuring and the transmission simulator method are presented. The overarching mathematical concepts are reviewed, as well as practical details needed to implement the methods. Various examples are presented to elucidate the methods, ranging from academic examples such as spring-mass systems, which serve to clarify the concepts, to real industrial case studies involving automotive and aerospace structures. The wealth of examples presented reveal both the potential and limitations of the methods.
