A detailed introduction to vibration based durability testing

CentraTEQ Vibration & Package Test Systems News and PR from CentraTEQ Vibration & Package Test Systems - Published 20 October 2022 CentraTEQ is offering ‘Good Vibrations’, a detailed introduction to vibration based durability testing as a digital download.
Good Vibrations is written by Ben Haest, M.Sc.Eng., Managing Director of QED, manufacturer of the Gnostic 64 ultra high speed contact measurement system. It is the result of many years of experience of training vibration testing engineers.
The book begins 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, and 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.

This is available to buy as a downloadable PDF or in CD format from CentraTEQ.
