摘　　要：超磁致伸缩材料作为一种新型、高效的功能材料在许多领域显示出良好的应用前景 ,但是由于其存在滞回、非线性等不足 ,限制了它的进一步应用。文章在分析超磁致伸缩现象产生机理的基础上 ,给出了其基于磁感应强度的控制模型 ,并通过分析和实验研究得出 :采用磁感应强度的控制方法可减小超磁致伸缩材料滞回 。As a new type and high performance functional materials,giant magnetostrictive materials has shown good application prospects in many fields.But its further application is restricted because of its drawbacks such as hysteresis and non-linearity.From the analysis of produce mechanism of giant magnetostrictive phenomenon,a control method is proposed based on flux density.The analysis and experiment results show that the hysteresis of giant magnetostrictive materials will decrease and the control precision of it will be improved if adopting the control method based on flux density.
