Vibration animation for a violin
This page shows the measured eigenmodes of vibration for a violin made by Antonio Stradivari. For the sake of the animation, the amplitudes have been greatly exaggerated and the frequencies slowed down (slow-motion display).
Eigenmodes of Vibration of a Violin
Example: Violin by Antonio Stradivari (1712)
Another way to evaluate the eigenmodes of vibration is to plot the "modal activity".
