Basics of Vibration Measurement

Frequency is a measure of how fast a body is vibrating and is used to identify the source of vibration Normally Frequency is expressed in shaft rotative speed If a vibration is at the same frequency as the shaft speed this will be 1X or 1 time shaft speed

734 MECHANIK NR 8–9/2017 Measurement of vibrations

Relative and absolute methods of bearing vibration measurement The methods of measuring the vibration of rolling bear- ings can be classifieddepending on whether the relative force is proportional solely to the velocity of the vibrating object [6] ing bearings are rarely used in the control of rolling bear- ings but more often in
