光电系统伺服稳定平台可靠性定性分析

Qualitative analysis of reliability on servo stabilization platform of electro-optical system

摘要: 以两轴四框架光电系统伺服稳定平台为研究对象，运用故障模式、影响及危害性分析（FMECA）以及模糊层次分析法，对伺服稳定平台的可靠性进行定性分析。在得到伺服稳定平台的关键故障模式和可靠性关重产品清单后，充分考虑人为主观判断的模糊性，继续深入分析关重产品对可靠性影响的重要度排序，以此作为后续可靠性设计和分配的重要参考。

Abstract: Taking the servo stabilization platform of two-axis and four-frame electro-optical system as the research object, the reliability of servo stabilization platform was qualitatively analyzed by using the failure mode, effects and criticality analysis (FMECA) and fuzzy analytic hierarchy process. After obtaining the critical failure modes and the list of reliability critical products of the servo stabilization platform, the fuzziness of human subjective judgment was fully considered, and the importance ranking of the impact of key products on reliability was further analyzed, which could be used as an importance reference for subsequent reliability design and distribution.
