研究了铁磁弹性板在均匀磁场中的屈曲问题.当外磁场垂直作用于板面时,在线磁弹性理论的框架上,建立了板的平衡方程,结合相应的边界条件,求解了平衡微分方程.接着讨论了板发生两种变形(反对称和对称变形)时的屈曲,并得到了屈曲时的临界磁场值.比较两种变形的临界磁场值,其结果表明对称变形时的屈曲磁感应强度高于反对称变形的磁感应强度.
The problem of buckling of the ferromagnetic elastic plate in a uniform magnetic field is studied. When the external magnetic field acts perpendicular to the plate surface, the equilibrium equation of the plate is established on the framework of on-line magneto-elastic theory. Combined with the corresponding boundary conditions, the equilibrium differential equation Then the buckling of two deformations (antisymmetric and symmetric deformation) is discussed, and the critical magnetic field values of the buckling are obtained.Comparing the critical magnetic field values of the two deformations, the results show that the flexural magnetic induction intensity of symmetrical deformation is high In the anti-symmetrical deformation of the magnetic flux density.
