Abstract :
A numerical dynamic and strong coupled model of giant magnetostrictive actuator was founded. According to the model and the measured magnetic characteristic of giant magnetostrictive material, the relation between the magnet field and the output displacement of the actuator was calculated by means of the finite element method. A comparison between the calculating result and the experimental one for the actuator was carried out and it was found that they were in agreement well. This indicates that the numerical dynamic model can be used for the design of giant magnetostrictive actuator.
