| Abstract(in English) | In recent years, giant magnetostrictive material has been using in the world. The material has characteristics of large strain, low Young's modulus and low mechanical quality factor. We measured the impedance of the magnetostrictive vibrator and calculated current dependencies of the parameter for equivalent circuit of the vibtator. Then, it is clarified that larger force factor and higher compliance are attained by giving lager magnetic field into the magnetostrictive rod along the axial direction. Also, we calculated electro-mechanical efficiency of the vibrator. That value reached to 90.7% at larger exciting magnetic field. |
