ASD researchers are developing computational methods for dynamics of systems of flexible structures that are interconnected. These are called multi-flexible-body dynamics.

Structural Dynamics and Vibration in Practice: An Engineering Handbook

As soon as I started reading Douglas Thorby's textbook, I felt it was different compared to the plethora of existing textbooks on structural dynamics focused on mechanical and aerospace engineering disciplines. The textbook is presented in 13 chapters, covering: Chapter 1: Basic concepts; Chapter 2: The linear single degree of freedom system: classical methods; Chapter 3: The linear single degree of freedom system: response in the time domain; Chapter 4: The linear single degree of freedom system: response in the frequency domain; Chapter 5: Damping; Chapter 6: Introduction to multi-degree-of-freedom systems; Chapter 7: Eigenvalues and eigenvectors; Chapter 8: Vibration of structures; Chapter 9: Fourier transformation and related topics; Chapter Random vibration; Chapter Vibration reduction; Chapter Introduction to self-excited systems; and Chapter Vibration testing.

These section titles indicate that the material is primarily theoretical and there is very little material related to practice, in particular concerned with civil and structural engineering, which is my field. Indeed, this book, as its author notes in the preface, is heavily biased towards the aerospace industry.

However, the theory covered is very much applicable to all branches of engineering, including structural civil engineering. With regard to this, I like the intelligibility of Thorby's writing, his superb mastery of the rather complex technical English used in the structural dynamics and vibrations world. Although Thorby, whenever possible, tries to explain things quite effectively using his own perspective, the key terminology used is precise and correct, which is quite hard to achieve. This is particularly so, considering Thorby's understandable despair with the inconsistent and ever-changing terminology often used quite loosely by the structural dynamics and vibrations community.

For example, he notes:. There are plenty of similar informative insights throughout the book, indicating deep understanding and knowledge of the field. Having said this, there are some weaknesses. These areas are usually neither explained nor written well in textbooks, and — alas — this one is no exception. In Thorby's textbook, physical sources of damping are mixed with their mathematical modelling, which is what is usually and quite confusingly done in other textbooks.

In principle, there is only dispersion and dissipation of vibration energy, and nothing else physically happening in real structures, which dampens them. Everything else is mathematical modelling of those two phenomena, and I am yet to see a textbook dealing with damping in this way explicitly. So what? Finally, the section on dynamic testing has almost no graphics and does not describe any practical activity required to do the testing, which is — surprise, surprise — all about hands-on work with some real structures.

It was refreshing to see that the graphics in the textbook are clear and consistently presented. Figures and illustrations are not the usual hotchpotch of inconsistent plots and drawings featuring many different sizes and styles in the same textbook , which are so common now in modern textbooks written by overbusy authors and commissioned by editors with overstretched publishing budgets.

Well done! The book contains rather few references. Although the textbook is written very clearly and it may be argued that a comprehensive list of references is necessary as a supplement, I feel that an opportunity has been lost here to provide further reading material. Personally, I would love to see what Douglas Thorby considers to be the seminal publications that inform the various topics he so nicely and confidently writes about.

Rather, this is a well-written standard textbook on the theory of structural dynamics and vibrations offering better than usual explanations of many key concepts that will serve its reader for many years to come.

This straightforward text, primer and reference introduces the theoretical, testing and control aspects of structural dynamics and vibration, as practised in industry today. Written by an expert engineer of over 40 years experience, the book comprehensively opens up the dynamic behavior of structures and provides engineers and students with a comprehensive practice based understanding of the key aspects of this key engineering topic. Written with the needs of engineers of a wide range of backgrounds in mind, this book will be a key resource for those studying structural dynamics and vibration at undergraduate level for the first time in aeronautical, mechanical, civil and automotive engineering. It will be ideal for laboratory classes and as a primer for readers returning to the subject, or coming to it fresh at graduate level. It is a guide for students to keep and for practicing engineers to refer to: its worked example approach ensures that engineers will turn to Thorby for advice in many engineering situations.

Structural Dynamics and Vibration in Practice

As vibration isolation and reduction techniques have become an integral part of machine design, the need for accurate measurement and analysis of mechanical vibration has grown. Using accelerometers to convert vibratory motion into an electrical signal, the process of measurement and analysis is ably performed by the versatile abilities of modern electronics. A body is said to vibrate when it describes an oscillating motion about a reference position.

This book is primarily intended as an introductory text for newly qualified graduates, and experienced engineers from other disciplines, entering the field of structural dynamics and vibration, in industry. It should also be found useful by test engineers and technicians working in this area, and by those studying the subject in universities, although it is not designed to meet the requirements of any particular course of study. No previous knowledge of structural dynamics is assumed, but the reader should be familiar with the elements of mechanical or structural engineering, and a basic knowledge of mathematics is also required.

The mode shapes are not normalized to any particular amplitude. Note that the free—free beam has zero frequency rigid modes. Example 8. One investigation considers straight lengths of steel pipe, installed with spacing, L, between support centers, as shown in Fig. It may be assumed that a separate investigation has shown the response in higher order modes to be negligible. Solution Part a From Table 8.

Попробовал добрести до двери. Меган скрылась во вращающейся секции, таща за собой сумку. Беккер почти вслепую приближался к двери.

ГЛАВА 21 Голос американца, звонившего Нуматаке по прямой линии, казался взволнованным: - Мистер Нуматака, в моем распоряжении не больше минуты. - Хорошо. Полагаю, вы получили обе копии ключа.

Это мощное тело принадлежало Грегу Хейлу. ГЛАВА 58 - Меган - девушка моего друга Эдуардо! - крикнул панк Беккеру. -Держись от нее подальше.
