On the Dynamics of an Innovative Actuator Based On Magneto-strictive Material

A novel type of actuator based on the magnetostriction phenomena is proposed. This model consists of a cantilever beam made of steel which is laminated with Metglas 2605sc as the magnetostrictive material. The beam deflects while it is located in a magnetic field, because of the shape changes in the magnetostrictive layer. This beneficial deformation can be used to design an actuator. The nonlinear Euler-Bernoulli beam theory is implemented by means of newton’s second law. The dynamic response of the proposed model of the actuator beam and specially the relation between the position of the beam tip under the influence of magnetic field and also the effect of the damping coefficient on the transient response and stabilization of the tip of the beam, which is assumed to be end effector, are obtained. The proposed model in this paper needs no connections and driving instruments and can be used remotely, moreover achieved nonlinear dynamical equations in this study can be used as a design tool for these kinds of actuators.
