Resonance curve

With the combination of StrobeCAM and LIMtrack the resonance curve is measured at a frequency sweep. In this example, a spring is excited on an electrodynamic shaker with 20-200 Hz. For the measurement of motion using LIMtrack, the spring is prepared with patter stickers.
The video shows the frequency sweep with the visualized marker movement.
The diagram shows the horizontal (U) and vertical (V) movement of the markers as a function of the excitation frequency.
