摘　　要：利用电磁仿真软件FEKO建立了某型电发火弹药模型和所需的电磁场环境,对某型电发火弹药的电磁耦合规律进行仿真分析。仿真结果表明,在弹体内部,引信位置场强与原场相比有所衰减,但是不如内部其他位置明显,而且比较稳定。弹体底部与外界场比较相似,特别在频率较高时更为明显;在弹体外部,不同情况下分别存在着沿z轴和x轴方向强弱交替的电场。The electric ignition ammunition model and typical electromagnetic field environment was established with FEKO electromagnetic simulation software. The electromagnetic coupling rules of certain type of electric ignition ammunition were simulated. The simulation results showed that inside the ammunition, comparing with the original field, the field strength of the fuze part is smaller, but the attenuation is not as obvious as other parts, and its stability is better; the electric field at the bottom of the ammunition is similar with the environment, especially when the frequency is high; outside the electric ignition ammunition, the electric field can change in z and x direction in different cases.
