A structure will have a resonant frequency in each of its 3 directional planes (x, y and z, or as we call them, horizontal, vertical and axial). Resonance serves to amplify the vibration due to whatever vibration force is present at (or near) that resonant frequency. It is important to note that resonance does not cause vibration - it amplifies it.

In the ambient vibration survey the floor dynamic excitation is provided by the environment in which it resides. Vibration responses to this kind of excitation are acquired over a grid of test points covering the floor area of interest. This grid needs to be dense enough to describe all of the likely floor mode shapes in sufficient detail.

The final design for the crusher stand was a significant improvement over the original design, which was likely to have had potentially damaging issues with excessive vibration. Rectifying such issues once the structure has been built would be an extremely expensive exercise, not to mention the cost of lost production due to machine down time.
