超磁致伸缩电-机转换器的数学模型及其应用

Modeling of Giant Magnetostrictive Actuators and Its Applications

超磁致伸缩电-机转换器具有许多优点,并在机电领域显示出良好的应用前景。众多学者建立了大量的磁致伸缩模型,但这些模型种类繁杂,每种模型仅适合特定场合,急需对这些模型进行梳理。文中对超磁致伸缩电-机转换器的典型模型进行分析,比较了这些模型的预测效果与实测结果,最后给出这些模型在超磁致伸缩电-机转换器中的适用场合,为超磁致伸缩电-机转换器的优化设计、整体性能预估、控制及使用提供参考。

The advantages of giant magnetostrictive actuators have been widely accepted, which makes it demonstrate good ap- plication prospect in the mechanical and electrical domain. Many scholars have established multitudinous models for giant magne- tostrictive actuators, but each model was only suitable for specific occasions, these models are needed to be sorted. In this paper, the forecast results of several typical models, which is for giant magnetostrictive actuators, and its measured results were compared. The applicable occasions of these models were given through analysising advantages and disadvantages of each model. The investigation provides basic theoretical guidance for optimization design and integrity property analysis as well as controlling and using the giant magnetostrictive actuators.
