摘要
超磁致伸缩换能器工作时同时受机械力场和电磁场的双重作用,特性必然受机械结构参数和电源特性的双重影响,为寻找最佳的机械结构参数和电源特性参数,必须建模研究。讨论超磁致伸缩换能器的建模方法,为换能器的设计、研究提供借鉴。
This kind of transducers applied with giant magnetostrictive material can change great electric power into ultrasonic vibration. Its properties were influenced by mechanics parameters and power source quality. In order to seek the best parameters of mechanical structure and power source, we should make the dynamic model of giant magnetostrictive transducers. This paper presents the structure,principle and two subsistent dynamic model of transducers with new GMM, meanwhile analyses the characteristics about two established model in detail.
