| Abstract: | The physical medel of the coupling system of the inspecting apparatus is established and the equivalent circuits for the coupling system is derived by means of resistance analysis method.The dcctrical and mechanical pararneters of the TbxDy1-xFe2-x material such as resonance frequency, anti-resonance frequency and megnctomechanical coupling coefficient are obtained with test apparatus fabricated by ourselves.The experimental results provide valuable basis for the further research and manufacture of supersonic transducer. |
