On the Issue of Using the Developed Software in the Educational Process for the Study of Acoustic Paths of Magnetostrictive Displacement Transducers

The article is devoted to the research of the processes arising during the formation, translation and reading of information signals in the acoustic paths of magnetostrictive linear and angular displacement transducers. Mathematical models are given that make it possible to calculate the magnetic fields of annular permanent magnets and those formed by current pulses when they flow in a waveguide medium. To calculate the magnetization of the waveguide, a numerical method was developed that allows taking into account the magnetization of the waveguide material at a previous time. Mathematical models are also given to calculate the parameters of the magnetic flux of the solenoid and the output signal. Mathematical models for calculating permanent magnet magnetic fields, the developed numerical method and mathematical models for the formation of magnetic flux and output signal were implemented in the developed software used in the educational process. The research results, as well as refined and developed methods for calculating magnetic fields and the numerical method can be used to study magnetostrictive devices both at the stage of their design and operation, which reduces their final cost. It should also be noted that the article does not address issues related to the processing of the output signal, which provides opportunities for further research and further modification of the software.
