| 摘 要： | 可靠性是飞机设计的重要指标,现代民用飞机电传操纵系统的伺服作动系统普遍采用余度技术,传统的可靠性分析方法无法描述其动态过程。针对主备结构和三余度结构2种不同的民用飞机伺服作动系统方案,应用马尔可夫过程对其分别建立了可靠性模型,并仿真分析比较了两者的可靠性及故障覆盖率对系统可靠性的影响,对实际中系统方案的选择提供了理论依据。

| Abstract: | Reliability is an important index for civil aircraft. Servo-actuation systems for modern civil aircraft with FBW(fly-by-wire)use redundancy technology widely and traditional methods of reliability analysis cannot describe their dynamic process.Reliability models are developed using the markov process for dual-redundant(primary/backup)and triple-redundant servo-actuation systems.A simulation is conducted to analyze and compare reliabilities and influences of fault coverage on system reliability for the two systems. |
