柔性可靠性与故障诊断处理综合设计技术

针对现代卫星高可靠、长寿命的要求,从卫星系统整体角度出发,根据卫星数字化系统/设备的特点,应用网格技术和多学科综合技术实现卫星内部、甚至卫星个体之间的柔性重组,提高卫星及星座的系统可靠性.提出柔性可靠性技术、测试技术和故障诊断与处理的融合技术,将可靠性、测试性和故障诊断与处理的设计分析与产品功能/性能设计紧密结合,建立综合应用的设计分析模型,实现一体化设计,并尝试对此进行综合应用仿真,以达到卫星数字化系统/设备简单、经济和高可靠的目的.

Integrated flexible reliability and fault diagnosis design technique

In order to meet the demand that modern satellite be high-reliability and long-life,flexible restructuring was executed among the components insides atellite or among the satellites in a mission group,by means of grid and multidisciplinary technology,based on characteristics of digitalized system or equipment of satellite and over-all properties of system.Thus system reliability of satellite or satellite group could be increased.A technique that integrates flexible reliability design,testing and fault diagnosis/recovery processing was put forward,and design & analysis to reliability,testability and fault diagnosis/recovery was combined with design to function/performance of products.The corresponding integrated design & analysis model was established,and simulation for application was carried on.Therefore,the digitalized system or equipment of satellite could be ensured simple-structured,low-cost and reliable.
