Abstract
An active control model of an anti-vibration device is analyzed using a coupled electromagnetic and structural finite element technique, The model consists of two parallel conducting wires moving in a uniform m agnetic field, Displacement and velocity of the wires are detected and transformed into voltages, Those voltages are fed back to each wire t o control the motion by Lorentz force, Calculated response of the moti on is shown to agree with the theory of the equivalent mechanical mode l.
