Research on Integrated Flexible Cable Technology for Batch Production of Communication Satellites
摘要
Abstract
In order to meet the urgent need for large-scale batch-production and networking of communication satellites,and to solve the problem of poor consistency,low reliability and long delivery cycles of traditional cable networks depend heavily on manual operations,the flexible ca-ble network technology for communicationsatellite batch-production is studied in this paper.Firstly,the physical and electrical properties of flexible materials are explored under space-flight conditions.Materials and processes of flexible cable networks are selected and verified for com-munication satellites.Then,flexible cables are designed for a certain-type communication satel-lite.The traditional cable design concept is broken.The integrated layout concept is introduced.The 3D modeling is carried out for flexible cables of the entire satellite.Next,the signal flow di-agram of the entire satellite cable network is sorted out.Top-level design is conducted for signal flow directions.Finally,electrical properties are analyzed.The items include transmission im-pedance,layer structure,copper thickness,shielding method and grounding strategy.Parame-ters of Electronic Design Automation(EDA)rules are output.These parameters are used for flexible cable layout design.Experimental results show that the flexible cable have good trans-mission effects on 422,Controller Area Network(CAN)and power signals.It satisfies the standards of vibration tests and thermal-vacuum tests,and have favorable batch-production and assembly capabilites,basically meeting the demands of signal transmission and automated mass production in subsequent batch-production.关键词
