航天故障的成因分析与诊断技术

由于航天领域是一个高风险的领域，即使是局部环节的微小故障也会带来巨大经济损失或灾难。因此，分析航天故障成因和研究航天故障检测、诊断与防范技术，具有十分重要的理论意义与工程价值。以航天工程为背景，从系统、过程、技术环境和人机系统复杂性等5个方面归纳了航天故障产生的原因，剖析了航天故障的典型特点，分析了建立航天检测与诊断方法的技术难点，并就若干类型的航天故障提出了检测与诊断的技术研究方向．

Analysis and Diagnosis of Faults in Spaceflight Engineering

?Spaceflight is a new field with high risk. Even if a local and tiny fault arises, the consequence and sequential effects are terrible and disastrous. So, it is necessary and valuable for us to analysis why faults arise and to explore some new technologies to deal with faults. Five sources of faults are described under the background of spaceflight engineering, some typical features are analysed, the difficulties are pointed out for constructing algorithms of faults detection and diagnosis (FDD). At the end some new tendencies are suggested to study the faults in spaceflight engineering.
