Vibrations, Dynamics And Structural Systems

The Aim ofthe 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 increas­ ing, the machine mass and damping is reduced. Consequently, unwanted vibra­ tions can have very serious effects on dynamic systems.

The second volume is about modal analysis, computational methods for large eigenvalue problems, analysis of frequency response data by nonparametric methods, identification of dynamic structural parameters, dynamic model reduction and test-analysis correlation.

This text addresses the modeling of vibrating systems with the perspective of finding the model of minimum complexity which accounts for the physics of the phenomena at play. The first half of the book (Ch.1-6) deals with the dynamics of discrete and continuous mechanical systems; the classical approach emphasizes the use of Lagrange's equations.
