很多复杂系统(如汽车、导弹、飞机等)已经开始采用大量的线缆束来传输信号,线缆束的EMC问题越来越突出。为保证系统的电磁兼容性能,就必须要对线缆的串扰、辐射以及抗干扰等特性进行仿真或测试。FEKO Suite6.1.1软件提供强大的Cable Modeling功能,提供常用形式线缆(如:单线、双绞线、排线、同轴线、任意线缆束等),支持理想屏蔽(Solid-Schelkunhoff)和编织网屏蔽层(Braided-Kelly)。本文采用FEKO软件的矩量法与传输线法的混合仿真技术分析了几种工程上常用形式线缆的阻抗、辐射以及抗干扰等特性。
Many complex systems (such as cars, missiles, aircraft, etc.) have begun to use a large number of cable bundles to transmit signals, cable bundles EMC issues become more and more prominent. To ensure the EMC performance of the system, it is necessary to simulate or test the crosstalk, radiation and anti-interference characteristics of the cable. The FEKO Suite 6.1.1 software provides powerful Cable Modeling capabilities with common forms of cable (eg single wire, twisted pair, flat cable, coaxial cable, optional cable bundle, etc.), support for Solid-Schelkunhoff and braiding Braided-Kelly. This paper analyzes the impedance, radiation and anti-jamming characteristics of several commonly used forms of cables by using the hybrid simulation method of the Moment method and the transmission line method of FEKO software.
