Abstract
In order to accurately calculate eddy current loss of the rod-shaped giant magnetostrictive material, improve the giant magnetostrictive actuator control accuracy of displacement, an eddy current loss model of rod GMM that considering the skin effect was established. Firstly, the traditional eddy current loss of rod-shaped GMM was deduced, then discussed the influence of the skin effect for the inside magnetic field distribution of GMM rod, finally analysed the temperature characteristics of GMA through the comsolmultiphysics finite element numerical analysis method. Compared with traditional eddy current loss, under low frequency the two methods has same result, but under high frequency the new model can be more accurately calculate the eddy current loss of rod-shaped GMM. The research result has a great significance for improving the control precision and advancing the study of eddy current loss of GMA.
