| Abstract: | The output characteristic of GMA mainly depends on the distribution of magnetic field in Giant Magnetostrictive Materials.Therefore,making numerical analysis of magnetic field in GMA is of great significance to estimate the working performance parameters of GMA in advance.An axial symmetry model of GMA is built in this paper.Based on it,the magnetic field of the actuator is analyzed with finite element method,and the extension of giant magnetostrictive rod is calculated according to the analysis results.Finally,the static characteristic of GMA is tested.The experimental results show that the built finite element model and the analysis method are reasonable. |
| Keywords: | giant magnetostrictive actuator finite element analysis static characteristic |
