固体发动机失效树定量分析法

METHOD OF FAULT-TREE QUANTITATIVE ANALYSIS FOR SOLID ROCKET MOTOR

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——征求意见评分法。通过对某型号发动机试样阶段结构可靠性实例分析,得出了较满意的结果。

Based on the existing problem of determining the failure probabilities of base events in solid rocket motor fault tree quantitative analysis, an engineering method of 'Solicitation Opinions to Give Marks' is put forward to determine the failure probability. And a more satisfied result is obtained by analysing the living example of the structure reliability for some solid rocket motor at the test sample stage.
