Numerical Analysis for Vibration of Magnetostrictive Actuator

摘要：

The dynamic behavior of the actuator is described as the periodic vibration of a magnetostrictive rod excited by the input harmonic alternating current. The governing equation and boundary condition are of time periodically variable coefficient. In the present work finite difference scheme and transfer matrix method with high performance is developed to simulate numerically the respond of the output displacement at the pusher of actuator to the input exciting current. The numerical results indicate that the response of displacement is of periodic and of double frequency. For control applications of magnetostrictive actuator, the relation curve between the amplitude of output displacement and the peak input current is given.
