舰船双绞线电缆耦合影响预测与仿真

摘要

Aiming at the cable coupling phenomenon in ship engineering, the electromagnetic coupling effects on the twisted-pair cables are discussed. It formulates an distributed parameter model for the unit length of twisted-pair cables. And the effects of capacitive coupling and induced coupling on twisted-pair cables are analyzed for establishing the numerical prediction model of the coupling effect on twisted-pair cables. The simulation results show that the induced coupling can be evidently depressed when the terminal is imbalance, while the capacitive coupling can be also depressed when balancing the terminals.%针对舰船工程中的电缆耦合问题,着重探讨双绞线电缆的电磁耦合影响.提出了双绞线电缆单位长度的分布参数模型,分析了容性耦合与感性耦合的影响,并由此建立了双绞线电缆的电磁耦合数值预测模型.仿真结果表明,在非平衡终端情况下,双绞线能够显著减小感性耦合；通过平衡双绞线的终端,能够消除容性耦合.
