Considering the environmental stress characteristics of storage conditions, Fault Mode Mechanism and Effect Analysis (FMMEA) method is introduced to Dynamic Turned Gyroscopes (DTG) to determine the affecting stress type and the weak component. The analysis result shows that the temperature stress is confirmed as the most important influencing environmental factor, related to the performance degradation...
Failure Mode, Mechanism and Effect Analysis (FMMEA) is a reliability analysis method which is used to study possible failure modes, failure mechanisms of each component, and to identify the effects of various failure modes on the components and functions. This paper introduces how to implement FMMEA on the Single Board Computer in detail, including system definition, identification of potential failure...
With the deeply insight into the research on prognostic and health management(PHM), very little attention has been focused on conducting validation and performance evaluation in the airborne PHM systems. According to the designing flowchart, three validation methods are proposed with the sample implementation. In this paper, a dynamic semi-physical validation framework for the flight control system...
Accurate fault prediction or remaining useful life (RUL) estimation can obviously reduce cost of maintenance and decrease the probability of accidents so as to improve the performance of the system test and maintenance. At the same time, it is difficult to apply the model-based methods for fault prediction in most applications for complex systems. Due to continuously improving of automation, increasing...
