Theoretical and finite element models of maglev actuator are both established. Magnetic conductive rubber is added into the actuator to improve its performance. Numerical simulations and experiments show that adding conductive rubber increases the output force-power ratio while reduces the dynamic response slightly.

Active Vibration

In this paper for the first time, active vibration control of rotating laminated composite cylindrical shells embedded with magnetostrictive layers as actuators by means of first-order shear deformation theory is studied. Vibration equations of the rotating shell are extracted using Hamilton principle considering the effects of initial hoop tension, Coriolis, and centrifugal forces. The vibration differential equations are reduced to algebraic ones through Galerkin method. The validity of the study is proved by the comparison of some results with the literature results. Eventually, the influence of several parameters on damping characteristics and vibration responses are investigated in detail.
