Abstract :
The dependencies of displacement on current under different variable loads for giant magnetostrictive actuators are computed by using the finite-element method and measured. It is found that the computed result is in agreement with the measured one. This indicates that the finite-element model is valid for computing the displacement for actuators under variable load, and it can be used to design actuators.
