摘　　要：针对电子安全系统中高压电容放电过程中产生的瞬态电磁场对电子安全系统中的电磁敏感器件产生的强电磁场干扰的问题,提出了电子安全系统电磁屏蔽方法。即在引信壳体尺寸和重量符合要求的情况下,尽量选择厚度厚,电导率和磁导率大的金属材料来对引信高压放电回路进行屏蔽。仿真结果表明该方法切实可行,能有效选择合适的屏蔽材料对电子安全系统大电流放电产生的电磁干扰进行有效的屏蔽。In order to solve the problem of strong electromagnetic interference caused by the transient electromagnetic field in the process of high voltage capacitor discharge in the electronic safety system,an electromagnetic shielding method for the electronic safety system was proposed.That is,under the condition that the size and weight of the fuze shell meet the requirements,the metal material with thick thickness,high electrical conductivity and magnetic permeability should be selected as far as possible to screen the high voltage discharge circuit of the fuze.Simulation results show that this method is feasible and can effectively select suitable shielding materials to effectively shield the electromagnetic interference caused by large current discharge in electronic safety systems.
