讨论超磁致伸缩电—机械转换器集中参数机电模型及滞回特性模型建模方法。建立的超磁致伸缩电 -机械转换器集中参数模型在中低频段能反映其动态行为 ,滞回特性模型能有效描述电—机械转换器的电流—位移滞回关系。仿真结果与实验特性能很好地吻合 ,表明提出的 2种模型是有效的。
Discuss the electromechanical model and the hysteresis model modeling method of the giant magnetostrictive electro-mechanical converter. The established model of GMA-CM converter can reflect its dynamic behavior in low and medium frequency range. The hysteresis model can effectively describe the current-displacement hysteresis relationship of the electro-mechanical converter. The simulation results agree well with the experimental ones, which shows that the two proposed models are effective.
