摘　　要：针对磁引信在应用中遇到的壳体屏蔽问题 ,提出将引信体近似为回转椭球壳体模型 ,从理论上详细地分析了椭球壳体在均匀磁场中的屏蔽效应 ,给出了相应的屏蔽系数公式 ;并通过试验验证了理论分析的正确性 .该研究分析对磁引信体的选材。Aiming at the magnetic field shielding effectiveness in magnetic fuze application, the spheroidal shell is brought forward to act as the fuze body approximate model. The magnetic shielding effectiveness of the spheroidal shell immersed in a uniform magnetic field is analyzed theoretically and the shielding coefficient expressions are induced. Moreover the correctness of the theoretical analysis is validated by experimentation. This research is of significance for the selection of magnetic fuze body's material, configuration design and the measured magnetic signal process.
