| 摘 要： | 应用在应力作用下的磁致伸缩系数与磁化强度的关系，建立了磁致伸缩的计算模型，结合器件的实际结构，采用有限元方法，计算了磁致伸缩棒在应力作用下的磁致伸缩，计算结果与实验值符合，分析表明，采用该模型得到的计算结果能够较准确地反映材料在工作状态下的磁致伸缩。

| Abstract: | A computed of magnetostriction for the giant magnetostrictive materials rod compressived was described according to the relation between the magnetostriction and magnetization and by using the finite element method. The magnetostriction of the magnetostrictive rod compressived was computed and the calculation results are in agreement with those of experiment. |
