Abstract
This paper presents a centrifuge with a system of automatic elimination of vibrations of the centrifuge that are generated by its unbalance. The rotor of the centrifuge spins around an axis with a fixed point. Two or more balls inside the ring which is fixed to the rotor can automatically eliminate its vibrations. The balls, also called free elements, would be able to change their positions inside a ring in such a way to compensate the dynamic forces. This paper presents equations that define the behavior of the system and also the diagrams that present the vibration of the rotor and the behavior of the balls when the unbalance is present. This paper explains the final positions that the balls occupy and when they are dynamically stable.
