INVESTIGATION OF MAGNETIC CIRCUITS OF A MAGNETOELASTIC CONVERTER WITH MAGNETIC FIELDS OF VARIOUS FREQUENCIES
Аннотация
The article is devoted to the study of magnetic circuits of a magnetoelastic converter, the principle of operation of which is based on the magnetomodulation effect. A mathematical expression of the magnetization curve of the magnetic circuit of a magnetoelastic converter is obtained when magnetized by magnetic fields of various frequencies (direct and alternating) currents. The influence of the variable and constant components of magnetic induction on the nature of the magnetization curve is estimated. The obtained magnetization curves of a magnetic circuit with longitudinal modulation and their approximation formulas can be successfully used to calculate magnetomodulation magnetic circuits, where a constant magnetic field corresponding to the region of the magnetization curve above the Rayleigh one is modulated.
