摘　　要：为了研究某型弹体的电磁耦合规律,利用电磁仿真软件FEKO建立弹体模型.研究得到:在弹体内部腔体存在谐振频点,存在电磁耦合场的增强区域;引信内部存在谐振频点,存在电磁耦合场的增强区域;弹体与引信壳体的屏蔽效能随频率变化的规律.In order to study the electromagnetic coupling law of one typical proj ectile body,electromagnetic simulation software FEKO is used to set up a model for the proj ectile body.We find that inside the proj ectile body there are resonance frequencies and electromagnetic coupling enhancing areas;inside the fuze there are resonance frequencies and electromagnetic coupling enhancing areas;and the law that the shielding efficiency of proj ectile body and fuze shell vary with frequency.
