An exciter, a mass and a force-transmitting medium in-between: this is how every vibratory system looks. If a periodic excitation is added, resonance may occur – and along with it a particularly high amplitude of the vibration.
This is only seldom desired for applications in mechanical engineering. Smooth operation is gone quickly.
The white paper gives answers to these questions:
