采用有限元方法对磁致伸缩棒的磁机械特性进行了建模。优化的形状和尺寸的重型磁致伸缩致动器。由于磁致伸缩材料的特性是非线性的，建模方法使用迭代过程。为了利用磁致伸缩棒的实验特性λ（H），提出了一种新的建模方法。
Finite Element Methods are used to model the magneto-mechanical characteristics of a magnetostrictive rod. Optimisation of the shapes and dimensions of the heavy magnetostrictive actuator is done. As magnetostrictive material characteristics are non-linear, the modelling methods use an iterative process. A new modelling method has been developed so as to use the available experimental characteristic of magnetostrictive rod : lambda(H).
