采用Fourier变换方法对广义Flamant载荷作用半平面铁磁结构弹性变形诱导的静磁场分布进行求解,得到的表达式经退化与集中力作用情形的扰动静磁场分布表达式相同.数值结果表明,载荷分布形式通过影响结构的弹性变形进而影响扰动磁场分布的形貌和大小,扰动静磁场分布的形貌与载荷极大值的分布区域有直接关联,扰动静磁场分布的最值与作用力的大小正相关;扰动静磁场强度的法向分量的最值随着与结构表面的距离的减小而增大,随载荷分布尺寸的增大而增大.
The magnetostatic field perturbed by the elastic deformation of half plane ferromagnetic structure under the generalized Flamant load in earth magnetic field is solved analytically by the Fourier transform method. The numerical results show- (1) the distribution of the generalized Flamant load affects the elastic deformation of the structure, and further affects the distributions and the values of the magneto- static field perturbed by elastic deformation; (2) the distributions of magnetostatic field are directly related to the distributions of the maximum load area, and the values of magnetostatic field are positively associated with the values of the forces; (3) the magnetostatic field perturbed by elastic deformation increases with decreasing distance away from the structure surface and increasing load distribution size.
