    A new semiactive coupling element working on the principle of squeezing two concentric films formed by classical and magnetorheological liquids has been proposed to achieve the optimum attenuation of the lateral vibration of rotors. The damping effect is controlled by changing the magnetic field induction. The steady state solution of the equations of motion is obtained by application of a collocation method and its stability is evaluated using the Floquet theory. The newly proposed controllable damping device enables to minimize amplitude of the rotor vibration by adapting the damping effect to the current operating conditions.
