In this video we have animated two different vibration patterns of an historic artefact, the Oseberg Viking ship.
What you see is the deflection pattern of 60+ measurement points on the ship coupled together to show how the ship moves under de facto load conditions. Real deflections is in the micro meter range so here they have been magnified for us to see.
In this case the load is caused by floor vibration due to visitors walking more or less in random around the artefact.
This animation/analysis can be used for improving computer models of the ship’s structural dynamics.
