可控电磁引信的设计及其与坦克磁场相互作用的数值分析

以磁引信炸雷探测并攻击坦克等铁磁目标为应用背景，在对坦克磁场特征进行分析的基础上，设计了一种针对目标磁信号强弱可以灵活调控灵敏度的磁引信，分析该引信的可控载流线圈与坦克磁场的相互作用，计算出引信线圈在坦克磁场中所受到的偏转力矩，并对该力矩在三维空间中的分布情况进行了模拟，根据数值计算结果提出了提高探测灵敏度的基本方案，为后续试验研制该类新型磁引信及“磁隐身”坦克提供参考。

Design of Controlled Electromagnetic Fuse and Its Numerical Analysis of Interaction with Tank's Magnetic Field

With the application background of the mine with electromagnetic fuse detecting and attacking such iron-magnetic targets as tank, based on the analysis of the tank＇ s magnetic field features, a kind of electromagnetic fuse whose sensitivity can be controlled according to the magnetic signal intensity of target is designed. The interaction of the controlled carrier choke coil with the tank＇ s magnetic field is discussed, the deflection torque acting on the fuse＇s coils in the tank magnetic field is calculated, and the distribution of the torque in three-dimensional space is simulated. According to the numerical calculation result, the main scheme of raising the detection sensitivity is provided, which offers reference data for developing the new electromagnetic fuse and the ＂magnetic stealth＂ tank in follow-up experiments.
