Quality Electronics Design S.A. (QED) have launched a new online book, ‘Good Vibrations’, it is a detailed introduction to vibration based durability testing. Originally released at the end of March 2014 it has now also been made available as a CD version.
The book has been written by Ben Haest, M.Sc.Eng., Managing Director of QED and is the result of many years of experience, training vibration testing engineers on the one hand and in depth research on the different subjects on the other hand. The book aims to clear up many of the misunderstandings in the field, in particular responses such as “we always did it like that” or: “we are told…”, in these situations the information is third hand and a true understanding is lacking.
The pdf version of the book allows a quick search on any issue explained in the book and allows an easy installation on your laptop or on your vibration control system. The book offers high resolution colour pictures, graphs, formulae, tables and examples on more than 380 pages.
The book starts with an introductory explanation about fatigue damage due to vibrations, this is the basic theory behind vibration testing and explains what is happening to the Device Under Test (DUT) during a test.
Shaker testing is used in most industry sectors including Aerospace, Automotive, Transport, Military, Electronics ……. although the actual testing is carried out by vibration test engineers who will find this book invaluable it also provides an important reference guide for design engineers who specify tests and products. The norms and standards in the field of vibration testing are “the” reference for the definition of test specifications. However, the background and the language of the norms and standards are not always understood. Here the book is a bridge between the design department and the test lab.
As vibration testing for durability is a complex area where many disciplines of engineering meet, this is a unique document covering all aspects, including:
- Types of sensors
- Time domain and frequency domain
- Vibration control: random / sine / shock
- Dynamic range
- Power amplifier
- Shaker
- Head expander and fixture design
- Bolting, slip tables, combined systems
- Maintenance and calibration.
The book also discusses issues like the mechanical and the electrical installation of a shaker and the alternative solutions to improve the quality and the dynamic range of signal transmission. With respect to the installation of a shaker the energy losses are calculated and illustrated.
An accompanying free Excel® file gives the reader the tools for gRMS and maximum displacement calculations of a random profile as well as calculations of displacement, velocity and acceleration for a sine profile in addition to resonance.
