The existing satellite low-frequency cable network is mainly designed based on experience and specifications,which cannot effectively ensure the reliability of system operation,resulting in repeated cable signal transmission problems.To this end,a physical simulation model for cable signal transmission is established based on finite element analysis,and the transmission characteristics of satellite low-frequency cables are studied.The influence of cable conductor specifications,characteristic impedance,shielding structure,etc.on cable transmission performance is studied through a combination of simulation and experiment.Effective prediction and prevention of cable signal transmission problems can be achieved during the design phase.Introducing finite element simulation analysis and experimental verification into the design of satellite low-frequency cable networks,it enriches the design methods both theoretically and practically,forms an effective design system,improves the design level,and increases design reliability.
