Abstract

The emphasis of this paper is to study the high frequency dynamic characteristic of high-power transducer based on giant magnetostrictive material. A prototype of high-power magnetostrictive transducer using in kHz magnitude frequency situation is introduced. The accurate inductance relation in magnetostrictive transducer is calculated, and its dynamic impedance characteristics of the transducer are summarized. Then, the experimental test-bench is set, the impedance-frequency characteristics and high frequency dynamic characteristics are discussed. The results show that magnetostrictive transducer has predominant mechanical strain effect at mechanical resonance situation, its magnetostriction coupling coefficient can up to 0.592, and has 0.05mm output strain at 1200Hz frequency. Researches and its results in this paper can helps for the calculation and construction of magnetostrictive transducer using in high frequency application.
