Аннотация
В статье рассматривается вопрос о магнитоупругой деформации конструктивного микроэлемента в виде токо-ведущей пластины под действием электродинамических сил с учетом ортотропии свойств проводимости в магнитном поле. Проведен анализ магнитоупругих уравнений в Лагранжевой форме, представлена система решающих уравнений, описывающая напряженно-деформированное состояние пластины ударного кольца, и сформулирована соответствующая нелинейная краевая задача. Анализируется учет влияния пондеромоторной силы Лоренца при исследовании напряженно-деформационного состояния неподвижной кольцевой пластины.
Maqolada magnit maydonida oʻtkazuvchanlik xossalarining ortotropiyasini hisobga olgan holda elektrodinamik kuchlar ta’sirida boʻlgan tok oʻtkazuvchi plastinka shaklidagi konstruktiv mikroelementning magnitoelastik deformasiyalanishi masalasi qaralgan. Magnitoelastik tenglamalari Lagranj shaklida tahlil qilingan, hamda tokoʻtkazuvchi halqaviy plastinkaning kuchlanganlik–deformasiyalanganlik holatinini ifodalovchi hal qiluvchi tenglamalar sistemasi keltirilgan va mos chiziqlimas chegaraviy masala shakllantirilgan. Toktashuvchi halqaviy plastinkaning kuchlanganlik–deformasiyalanganlik holatini tadqiq qilishda ponderomotor Lorens kuchining tasirini hisobga olish tahlil qilingan.
The article deals with the issue of magnetoelastic deformation of a constructive microelement in the form of a current-carrying plate under the influence of electrodynamic forces, taking into account the orthotropy of the conductivity properties in the magnetic field. The magnetoelastic equations are analyzed in Lagrangian form, and the system of solving equations representing the stress-deformation state of the shock ring plate is presented, and the appropriate nonlinear boundary value problem is formulated. Taking into account the influence of the ponderomotive Lorentz force in the study of the stress-deformation state of the stationary ring plate is analyzed.
