为提高装甲防护性能,对被动电磁装甲中金属射流所受横向电磁力作用机理进行了研究。在等效电路模型基础上,建立了金属射流横向受力模型并具体讨论了射流微元所受横向电磁力随时间和位置的变化;结合虚拟源点理论,建立了不同速度金属射流微元穿过被动电磁装甲板后的横向偏移速度模型。计算显示,当电压达到35kV时,近一半长度金属射流产生有效偏移;试验中观察到了金属射流的横向偏移效果。上述研究进一步完善了被动电磁装甲对破甲弹的防护机理。
In order to improve the armor protection performance, the mechanism of transverse electromagnetic force on metal jets in passive electromagnetic armor was studied. Based on the equivalent circuit model, the lateral force model of metal jet was established and the variation of lateral electromagnetic force with time and position of jet micro-element was discussed in detail. Based on the virtual source point theory, Lateral migration velocity model after passive electromagnetic armor. The calculation shows that when the voltage reaches 35kV, nearly half of the length of the metal jet produces an effective offset; in the test, the lateral offset of the metal jet is observed. The above research further perfected the protective mechanism of the passive electromagnetic armor to Sunder Armor.
