| 摘 要： | 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.

| Abstract: | 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. |
