摘　　要：通过基于故障树的FMECA分析,归纳无人机危险事件,形成故障树顶事件;建立全机故障树模型,分析无人机全机1阶最小割集及其危害程度,确定薄弱环节并采取技术措施;对全机危险事件的安全性进行定量估算。This paper summarizes the hazard events of UAV by using FEMCA analysis based on fault tree so as to build up the top event of fault tree,analyzes one rank sets of UAV and their crises by modeling fault tree of UAV,verifies deficiency and takes corresponding actions,and quantifies the occurring probability of hazard events.
