舰船武器装备的电缆敷设耦合评估技术

The coupling evaluation for cable laying of ship weapon equipments

针对舰船武器装备的电缆敷设设计要求,着重探讨电缆敷设耦合的电磁兼容性影响。通过求解电缆外部场激励起的电缆内部响应,建立了典型的场对屏蔽电缆的电磁耦合模型。在此基础上仿真分析了某电缆上的感应电流、电压的幅频特性,仿真结果表明该电缆具备较大的电磁兼容安全裕度,可以作为电缆敷设的设计依据。

Aiming at the cable laying design requirements of ship weapon equipments,this paper discusses the EM coupling effects on the coupling of cable laying.A typical model is presented for the analysis of EM coupling effects of external electromagnetic fields on the shielding cable by solving the inner response inspired by the outer EM field.On the basis of it,the amplitude-frequency characteristic of inductive currents and voltages of some certain cables are simulated,which shows that these cables have large EMC safety margin,and helps to the design of the cable laying.
