作动系统健康状况对飞行安全影响的评估方法

机电作动系统的故障往往导致灾难性的后果。采用自上而下的设计思路，建立了机电作动系统对飞行安全影响的分析方法。综合机电作动系统故障模式及飞控系统故障模型，对机电作动系统进行故障模式及影响分析，用Monte-Carlo法对故障进行随机性仿真，求得机电作动系统的故障概率，应用极值理论计算飞行安全概率。仿真实验说明：该方法可以用做进行安全监控的依据。

Assessment methods of electromechanical actuation systems health situation impact on flight safety

Electro-mechanical actuation system failure often leads to disastrous consequences. Using a top-down design idea, this paper proposes electro-mechanical actuation system analysis approach of the impact on flight safety. This paper combines electro-mechanical actuation system failure mode and the flight control system failure model together. It obtains failure modes and effects analysis of electro-mechanical actuation system. It uses the Monte-Carlo method to obtain the electromechanical actuation system failure probability. Application of extreme value theory is used to calculate the flight safety probability. Simulation experiments demonstrate that this method can be used as the basis for security monitoring.
