Dear Alex,

Equipment vibrations are checked with an accelero-measuring device.

Have a look at:

A sound level-measuring device, equipped with an accelero-sensor, already does the trick.

Fourrier analysis equipment gives you the full information of the measured vibrations.

The knowledge of the theory behind the world of vibrations and oscillations is a must though, to understand what you are doing.

Before buying any equipment, define the vibration range, in which you want to measure.

Structural calculation analysis is more complicated. This is a coupled mass/stiffness issue, which requires the full knowledge of the vibration theory.

Natural frequencies are checked with exitation frequencies.

If these coincide, there will be resonance, unless the damping is sufficient.

Success
