Abstract. In connection to microwave
magnetostriction transducer the hypersound vibrations excitation in geometry of
normal magnetized ferrite plate is investigated. In quadratic approximation it
is obtained the system of two connected second order equations for
magnetization and elastic displacement maintained nonlinear three order
components which equivalent to model system of two connected oscillators. By
the analysis of vibrations time development and amplitude-frequency characteristics
it is found that the quadratic approximation is applicable to magnetization
angle precession as 40 degree. It is shown that quadratic approximation leads
to decrease of computer calculation time on two order value.
Key words: hypersound, nonlinear
vibrations, magnetoelasticity.
