基于FMEA的某雷达天线俯仰升降机构可靠性分析

Reliability analysis for bending and lifting system of one radar based on FMEA

通过对某型雷达天线俯仰升降机构的分析得出失效模式和影响分析模型。针对某型雷达天线俯仰升降机构的组成和工作过程、失效模式和影响进行了较为全面的探讨和研究,得出了某型雷达天线俯仰升降机构的各种故障模式,供对该型雷达结构的失效模式和影响进行定量分析参考。

In this thesis,the failure mode and effects analysis model is deduced by the study of the bending and lifting system of one radar.The failure mode and effect analysis method are used to analyze the radar bending and lifting system in detail.From this,all kinds of failure modes are gained so that the whole radar’s failure mode and effects analysis will be analyzed quantitatively.
