本文介绍了故障树底事件数据的几种收集方法,主要内容包括故障树分析(FTA)在引信中的应用,引信故障树底事件数据的重要性,引信故障树底事件数据收集方法,共介绍了六种收集方法,即:参考国外引信故障树底事件数据;从现有验收和鉴定试验中统计数据;从生产检验中获取数据;推算法;工程判断法。文中还介绍了榴—5引信故障树底事件数据的来源,并给出了榴—7、电—11引信的故障树底事件数据。
This paper introduces several methods of collecting fault tree event data. The main contents include the application of Fault Tree Analysis (FTA) in fuze, the importance of data of tree fault event in fuze, and the method of collecting data of tree fault events in fuze. The six collection methods, namely: the reference to foreign fuze fault tree event data; statistics from the existing acceptance and qualification tests; data obtained from the production test; estimation method; engineering judgment method. The paper also introduces the source of the tree-bottom event data of the 5-fuze fault, and gives the data of the fault tree-bottom event of the 7-Fu and 11-Fuze.
