title: Vibration Testing: Theory and Practice
author:  Kenneth G. McConnell 
description: "&#8230;is a good foundational text for engineers concerned with component vibration testing as it might relate to failure analysis, qualification testing, reliability testing, and machinery diagnostics. The book is well written and makes the presented concepts easy to understand. I recommend it both as an introduction to laboratory testing techniques for the relative novice and as a reference for experienced practitioners in the field."

  MEASUREMENT TECHNIQUES

  INTRODUCTION
  Earlier chapters describe equipment used in vibration measurements. For example,
  detailed information concerning transducers, their characteristics, and how these
  characteristics are influenced by environmental factors is given in Chap. 12.The var-
  ious measurement system components and the characteristics which determine their
  selection are described in Chaps. 13 and 14.The use of such measurement systems in
  vibration problems may involve only one or two engineers as in monitoring the con-
  dition of machinery in a factory (Chap. 16), in some problems in modal testing
  (Chap. 21), in measurements in building structures (Chap. 24), in measuring tor-
  sional vibration in reciprocating and rotating engines (Chap. 38), and in the balanc-
  ing of rotating machinery (Chap. 39). In contrast, in the aerospace industry, some
  measurement problems are so complex that teams of engineers and several divisions
  of the company may be involved
