Abstract:
Magnetostriction of transformer core plays a dominated role in the vibration of transformer equipment. In order to simulation the magnetostrictive effect, a equivalent magnetostrictive force model is introduced in this paper. Elongation-based models are used to deduce the magnetostrive force. Elongation-based models employ experimental data from magnestrictive elongation to bulid the relation between magnestrictive strain and magnetic flux density, and can be used for harmonic analysis. Magnetostrictive force on single slicion sheet is deduced by strain energy density and energy conservation principle. The force is applied on the single silicon sheet model to analysis the deformation caused by magnetostriction.
