What is Vibration Testing? Condition Monitoring Services defines it here:



Vibration refers to mechanical oscillations about an equilibrium point. The oscillations may be periodic such as the motion of a pendulum or random such as the movement of a tire on a gravel road.

Vibration is occasionally "desirable". For example the motion of a tuning fork, the reed in a woodwind instrument or harmonica, or the cone of a loudspeaker is desirable vibration, necessary for the correct functioning of the various devices.

More often, vibration is undesirable, wasting energy and creating unwanted sound – noise. For example, the vibrational motions of engines, electric motors, or any mechanical device in operation are typically unwanted. Such vibrations can be caused by imbalances in the rotating parts, uneven friction, the meshing of gear teeth, etc. Careful designs usually minimize unwanted vibrations.

The study of sound and vibration are closely related. Sound, or "pressure waves", are generated by vibrating structures (e.g. vocal cords); these pressure waves can also induce the vibration of structures (e.g. ear drum). Hence, when trying to reduce noise it is often a problem in trying to reduce vibration.

Our field technicians utilize CSI portable vibration analyzers to collect and analyze equipment vibration. New technology allows a one-time set up of certain online monitoring units for continuous streaming online real-time data of multiple machines.

CMS also has the resources to provide ultrasound testing in addition to regular vibration testing. Ultrasound is effective at identifying leaks, steam trap inspection, electric emission detection, and bearing issues in early stages. Ultrasound reaches beyond human hearing and typical vibration data collectors to give plant personnel a greater overall picture of equipment condition.

If your company is interested in training personnel to analyze vibration data, our line of Mobius Institute iLearn vibration training programs are some of the best training materials out there. We also provide online or on-site vibration training for Levels I, II, and III ANST certification.
