Abstract: Introduction was made to a new kind of double-rod magnetostrictive transducer. Analysis was made to the structure parameters which influenced on the device magnetic field distribution. According to the simulation analysis, the selected magnetizer material was finally determined as a silicon steel sheet with a thickness of 10 mm, and the diameter of the magnetostrictive rod was 10mm. Aiming at the optimization of the transducer structure, this paper designed a friendly and simplified user interface to provide convenience for calculation and analysis in the future.
Key words: FeGa alloy; magnetostriction; transducer; structure design; simulation analysis
