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 magnetic field. Displacement and velocity of the wires are detected and transformed into voltages. Those voltages are fed back to each wire to control the motion by Lorentz force. Calculated response of the motion is shown to agree with the theory of the equivalent mechanical model
