About this title

Synopsis:

During the 1980s the technology of modal testing became very widely practised in all those engineering disciplines where vibration and other dynamic phenomena affect the behaviour and performance of structures and machines. The techniques involved in carrying out a modal test were developed to a high degree of sophistication while the applications to which the results of these tests could be put became more numerous and more powerful. At the same time as the advantages of modal testing were being enjoyed by an increasing audience, some of the drawbacks of inexpert use of the technology were being learned and recorded. These experiences reinforced the need for a thorough understanding of fundamentals upon which modal testing is based, and of the detailed workings of the various phases and processes which make up a successful test.

In this book, all the steps involved in planning, executing, interpreting and applying the results from a modal test are described in straightforward terms. Efforts are made throughout to ensure that the reader understands the physics of the various stages as well as (if not before) the mathematics.

This edition has brought the previous book up to date by including all the new and improved techniques which have emerged during the 15 years since the first edition was written. The more powerful applications are developed in more detail than previously and some new topics have been introduced, notable amongst which are the application of modal testing to rotating machinery and the use of the scanning laser vibrometer.

Synopsis:

Modal testing is widely practised in all those engineering disciplines where vibration and other dynamic phenomena affect the behaviour and performance of structures and machines. In this book, all the steps involved in planning, executing, interpreting and applying the results from modal tests are described. The book includes all the new and improved techniques which have emerged during the 12 years since the first edition was written, especially those of signal processing and modal analysis. It develops the more powerful applications of modal testing in more detail than in the first edition, and introduces some new topics, including the application of modal testing to rotational machinery. The text includes exercises and worked examples to facilitate understanding of the subject.
