 Mechanical vibration is a difficult subject matter to master. The advanced practitioner must master sophisticated concepts in mathematics and physics in order to accurately collect and interpret vibration data. This has caused a major problem for industrial plants – the benefits of a mechanical vibration testing programme are well known, but far too many plants choose to avoid mechanical vibration testing because of the perceived complexity.

 

Topics covered in this article are:


 

  • The difference between frequency spectrum analysis and overall mechanical vibration analysis
  • Overall mechanical vibration analysis and severity scales
  • Crest Factor Plus (CF+): High frequency overall mechanical vibration analysis and severity scales

The article describes two mechanical vibration products – a mechanial vibration tester and a mechanical vibration meter - which are easy to use and able to overcome the complex issues relating to mechanical vibration.

 

Take note

  • Mechanical vibration is difficult to master.
  • Sophisticated concepts in mathematics and physics are necessary to accurately collect and interpret mechanical vibration data.
  • Many industrial plants avoid mechanical vibration testing because of its perceived complexity.
