| 摘 要： | 对动态磁致伸缩过程进行分析，并建立了超磁致伸缩换能器的等效动力学模型。应用Green函数得到换能器的固有频率值。讨论了超磁致伸缩材料径向振动对其纵向振动的影响。与弹性杆纵振模型的比较表明，等效集中参数模型简便有效，为换能器参数选择提供了设计依据。

| Abstract: | Equivalent dynamic model of giant magnetostriction transducer is set by means of analyzing dynamic magnetostriction. Based on Green Function, the natural frequency of model is obtained. The transducer working in non-resonance is simplified as equivalent integral parameters model, and effect of radial vibration on the longitudinal vibration of the transducer is discussed. This model in comparision with elastic-lever-model of longitudinal vibration expatiates that equivalent integral parameters model is simple and effective, which offers the bases for selection of parameters in designing transducer. |
