固体发动机失效树专家评分法

The Expert Grading Method for a Solid Motor Failure Tree

根据固体火箭发动机失效树定量分析中确定底事件失效概率存在的困难,提出了确定底事件失效概率的工程方法——专家评分法.用此方法对某型号发动机试样阶段结构可靠性进行了实例分析,得出了较满意的结果.

Because of being difficult to determine the failure probability of bottom events in the quantitative analysis of a solid rocket motor failure tree, an engineering method (,i.e expert grading method), which is used to determine the failure probability of bottom events, is presented. By using it, structure reliability of the some motor in its preproduction model stage has been analyzed and the more satisfied results obtained.
