对磁场中软铁磁梁板的弯曲问题进行了实验研究和理论分析。实验是在室温下的超导磁体内腔中进行的。铁素体不锈钢SUS 430在这里被用作弯曲试验的悬臂梁试样。实验表明，随着磁场的增加，偏转和应变的预测增加。理论分析是基于一个经典的板弯曲理论的磁弹性相互作用在软铁磁材料。数值计算了不同磁场和几何参数下的挠度和应变。将理论计算结果与实验结果进行了比较，在考虑磁场的情况下，两者吻合较好。
Experimental evidence and theoretical analysis are presented for the bending of a soft ferromagnetic beam plate in a magnetic field. The experiments were conducted in the bore of a superconducting magnet at room temperature. Ferritic stainless steel SUS 430 is here used as the cantilever specimen for bending test. The experiments show the predicted increase in the deflection and strain with increasing magnetic field. The theoretical analysis is based on a classical plate bending theory for magneto-elastic interactions in a soft ferromagnetic material. Numerical calculations are carried out, and the deflection and strain are obtained for several values of magnetic field and geometrical parameter. A comparison of the deflection and strain is made between theory and experiment and the agreement is good for the magnetic field considered.
