摘要

通过对超磁致伸缩材料的磁畴理论、磁滞非线性以及倍频现象的分析

提出了超磁致伸缩换能器驱动信号应具有减小磁畴惯性、削弱剩磁和消除倍频现象的能力;综合以上因素

确立了一种新的能够满足要求的驱动信号。实验结果表明:提出的换能器驱动信号的驱动效率要明显优于目前使用的方波信号和梯形波信号。提出的观点为换能器的驱动电路设计奠定了基础。

Abstract

By analyzing on magnetic domain theory

hysteresis nonlinearity and frequency doubling phenomenon of giant magnetostrictive（GM） materials

it is proposed that driving signal of giant magnetostrictive transduer should have the ability of reducing domain inertia

weakening remanent magnetization and eliminating frequency doubling phenomenon

combined with the above factors

a new driving signal which can meet the requirements is established.Experimental results show that driving efficiency of the proposed transducer is prior to that of the square wave and trapezoidal wave signals.The proposed viewpoint lays a foundation for drive circuit design of transducer.
