为探究影响金属射流欧姆加热效应的因素，在被动电磁装甲系统等效电路模型的基础上，根据虚拟源点理论建立金属射流的作用时间模型，进一步明确金属射流在侵彻被动电磁装甲过程中每部分射流微元的作用时间；结合金属射流的比作用量模型，利用 Matlab软件对金属射流的电流和比作用量波形随被动电磁装甲系统的电感、电容、电阻和充电电压的变化规律进行数值分析。仿真结果表明：随着系统电感的减小、电阻的减小、电容的增大和充电电压的增大，金属射流比作用量的峰值增大，有利于射流发生电爆炸。

In order to explore factors affecting ohmic heating action on jet,according to equivalentcircuit model of passive electromagnetic armor system,the mathematical model of the time ofpulse current acting on shaped charge jet is established based on the virtual origin concept.Theacting time of jet element is further defined in the process of jet penetrating passive electromag-netic armor.Combined with the specific action model,the current waveform and numerical valueof specific action variation rules along with passive electromagnetic armor system inductance,ca-pacitance,resistance and the charging voltage are analyzed by Matlab.The results show that whenreducing the inductance and resistance or increasing the energy storage capacitance and chargingvoltage,the peak value of specific action increases,it makes for the jet to occur in electrical explosion.
