航空电源系统FMEA自动化技术研究

以飞机电源系统为例提出了一种在系统设计阶段，利用系统动态性能仿真模型自动进行定量故障模式影响分析的方法。该方法将系统中各个元器件可能的故障模式计入系统的动态模型中，并进行系统仿真，再将系统故障状态下的仿真结果与其正常状态下的仿真结果进行比较，以量化判定每种故障影响的严重程度，从而实现故障模式影响分析的自动化。

STUDY OF FMEA AUTOMATION TECHNIQUE FOR AIRBORNE POWER SYSTEM

Advance an automatic quantitative analysis method of failure modes and effects analysis with system transient simulation in the system design stage, take a airborne power system as a case in point. Be in use of the method, every possible failure mode of elements and devices in the system is accounted to the system transient model and system is simulated. Then simulate results of the failure states, and the cruel level of every failure mode effect is determined in numerical quantities. Therefore the automation of failure modes and effects analysis is realized.
