摘　　要：提高安全性和可靠性是机载设备的设计重点,余度技术是系统或设备获得高可靠性的设计方法之一。当系统发生故障时,余度系统能够自动完成系统重构,继续带故工作,从而提高系统的任务可靠性和安全性。从余度数目选择、余度结构、余度管理及策略设计、余度系统的单点故障影响分析和共模影响分析等几方面介绍了机载设备余度设计方法,同时分析了余度设计对设备的有利和不利影响,具有一定工程实用价值。Improving safety and reliability is a design priority for airborne equipment,and redundancy technology is one of the design methods to obtain high reliability for systems or equipment.When the system fails,the redundancy system can automatically complete system re-configuration and continue to work with the fault,thus improving the mission reliability and safety of the system.The redundancy design method of airborne equipment is introduced from the aspects of the selection of redundancy number,redundancy structure,redundancy management and strategy design,single point failure impact analysis and common mode impact analysis of redundancy system.The favorable and unfavorable effects of redundancy design on equipment are also analyzed,which has some engineering pratical value.
