| 摘 要： | 利用电磁仿真软件FEKO建立了某型弹药模型和所需的电磁场环境,对某型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,中部位置由于金属连接底的影响,电场强度发生突变。弹药壳体顶部的电场与外界基本一致。内部引信位置电场强度与原电场强度相比有所衰减,但是不如内部其他位置明显。弹体内部电场强度在120 MHz和560 MHz处衰减较小;在弹体外部,存在着沿z轴和x轴方向强弱交替的电场。

| Abstract: | In order to study the electromagnetic coupling law of one ammunition,software FEKO was used to set up the ammunition model and typical electromagnetic field environment.The simulation result shows:inside the ammunition,field strength of middle part breaks because of the metal connecting bottom.The electric field at the top of the ammunition is consistent with the environment.Compared with the original field,the field strength of the fuze part is smaller,but it is not as obvious as other parts.The attenuatio... |
