| Abstract: | Based on the statistical analysis of the failure reasons both for aircraft landing gears lowing and raising and for emergency lifesaving devices, it is discovered that the failure modes in fastening position and seizure appear frequently among failure modes for operating mechanism. Therefore, we should pay more attention to the failure modes of fastening position and seizure. Due to the lack of the research of reliability analysis in this field, a variety of methods for mechanism with failure modes of fastening position and seizure are put forward in this paper. The method for connecting the formulation of the fault tree analysis with that of the single mode reliability analysis for mechanism components is also illaustrated. |
