Abstract. The rotational vibrations of elastic displacement in magnetostriction converter in conditions of orientational transition are investigated. It is described the total task geometry and motion equations for magnetization and elastic displacement. This equation system is resolved by Rounge-Cutta method. It is found the development of magnetic and elastic vibrations in time. It is shown that in orientational transition take place the precession of magnetization equilibrium position which causes corresponding elastic displacement vibrations. It is investigated the dependence of elastic displacement vibrations amplitude from normalized plate thickness. It is shown that this dependence has square character. It is described the mechanical analogy of considered dependence with bend of elastic beam. It is investigated the elastic displacement vibrations period from plate thickness. It is shown that this vibrations period is proportional to four degree of plate thickness. It is proposed the interpretation of period from thickness dependence on the basis of mechanical model rotational vibrations. On the basis of proposed period elastic vibrations displacement characteristics it is made the conclusion that elastic vibrations have rotational character. It is shown that the variation of system parameters in large degree confirms the rotational character of elastic vibrations.

Keywords: precession of magnetization, orientation transition, rotational vibrations.
