  • Description
  • Contents

this book is the result of over 20 years of research and development in vibration analysis. This hardbound volume contains 6 chapters and 375 pages of analytical descriptions of how frequencies are calculated, generated, measured and analyzed. These analytical descriptions are supported by empirical measurements of actual case histories. The new edition features review questions at the end of each chapter.

Chapter 1 - Introduction to Machinery Vibration
