Book Description
A practical approach to the application of viscoelastic damping materials to control vibration and noise problems in industrial structures, machinery, computer machinery, and vehicles. Assuming a basic understanding of mechanical engineering, the text covers implementation of theory, including material properties, dynamic structural response, design procedures and practical applications. Based on an understanding of both the properties of materials and the vibrational response of structures. Considers individual structures and the damping materials properties simultaneously. Includes extensive collection of data sheets for a large number of useful damping materials.

Book Description
The theory of linear damped oscillations was originally developed more than hundred years ago and is still of vital research interest to engineers, mathematicians and physicists alike. This theory plays a central role in explaining the stability of mechanical structures in civil engineering, but it also has applications in other fields such as electrical network systems and quantum mechanics. This volume gives an introduction to linear finite dimensional damped systems as they are viewed by an applied mathematician. After a short overview of the physical principles leading to the linear system model, a largely self-contained mathematical theory for this model is presented. This includes the geometry of the underlying indefinite metric space, spectral theory of J-symmetric matrices and the associated quadratic eigenvalue problem. Particular attention is paid to the sensitivity issues which influence numerical computations. Finally, several recent research developments are included, e.g. Lyapunov stability and the perturbation of the time evolution.

Book Description
Covering the whole spectrum of vibration theory and itsapplications in both civil and mechanical engineering, Mechanicaland Structural Vibrations provides the most comprehensive treatmentof the subject currently available. Based on the author s manyyears of experience in both academe and industry, it is designed tofunction equally well as both a day-to-day working resource forpracticing engineers and a superior upper-level undergraduate orgraduate-level text. Features a quick-reference format that, Mechanical and StructuralVibrations gives engineers instant access to the specific theory orapplication they need. Saves valuable time ordinarily spent wadingthrough unrelated or extraneous material. And, while they arethoroughly integrated throughout the text, applications to bothcivil and mechanical engineering are organized into sections thatpermit the reader to reference only the material germane to his orher field. Students and teachers will appreciate the book's practical,real-world approach to the subject, its emphasis on simplicity andaccuracy of analytical techniques, and its straightforward,step-by-step delineation of all numerical methods used incalculating the dynamics and vibrations problems, as well as thenumerous examples with which the author illustrates those methods.They will also appreciate the many chapter-end practice problems(solutions appear in appendices) designed to help them rapidlydevelop mastery of all concepts and methods covered. Readers will find many versatile new concepts and analyticaltechniques not covered in other texts, including nonlinearanalysis, inelastic response of structural and mechanicalcomponents of uniform and variable stiffness, the "dynamic hinge,""dynamically equivalent systems," and other breakthrough tools andtechniques developed by the author and his collaborators. Mechanical and Structural Vibrations is both an excellent text forcourses in structural dynamics, dynamic systems, and engineeringvibration and a valuable tool of the trade for practicing engineersworking in a broad range of industries, from electronic packagingto aerospace. Timely, comprehensive, practical--a superior student text and anindispensable working resource for busy engineers Mechanical and Structural Vibrations is the first text to cover theentire spectrum of vibration theory and its applications in bothcivil and mechanical engineering. Written by an author with over aquarter century of experience as a teacher and practicing engineer,it is designed to function equally well as a working professionalresource and an upper-level undergraduate or graduate-level textfor courses in structural dynamics, dynamic systems, andengineering vibrations. Mechanical and Structural Vibrations: * Takes a practical, application-oriented approach to the subject * Features a quick-reference format that gives busy professionalsinstant access to the information needed for the task at hand * Walks readers, step-by-step, through the numerical methods usedin calculating the dynamics and vibration problems * Introduces many cutting-edge concepts and analytical tools notcovered in other texts * Is packed with real-world examples covering everything from thestresses and strains on buildings during an earthquake to thoseaffecting a space craft during lift-off * Contains chapter-end problems--and solutions--that help studentsrapidly develop mastery of all important concepts and methodscovered * Is extremely well-illustrated and includes more than 300diagrams, tables, charts, illustrations, and more

Book Description
This book opens with an explanation of the vibrations of a single degree-of-freedom (dof) system for all beginners. Subsequently, vibration analysis of multi-dof systems is explained by modal analysis. Mode synthesis modeling is then introduced for system reduction, which aids understanding in a simplified manner of how complicated rotors behave. Rotor balancing techniques are offered for rigid and flexible rotors through several examples. Consideration of gyroscopic influences on the rotordynamics is then provided and vibration evaluation of a rotor-bearing system is emphasized in terms of forward and backward whirl rotor motions through eigenvalue (natural frequency and damping ratio) analysis. In addition to these rotordynamics concerning rotating shaft vibration measured in a stationary reference frame, blade vibrations are analyzed with Coriolis forces expressed in a rotating reference frame. Other phenomena that may be assessed in stationary and rotating reference frames include stability characteristics due to rotor internal damping and instabilities due to asymmetric shaft stiffness and thermal unbalance behavior.
