GO法在引信系统可靠性分析中的应用

Application of GO Methodology in Reliability Analysis of Fuze System

GO法是一种面向成功的系统可靠性分析方法。与故障树分析方法相比,对于流程性系统和有时序系统的可靠性分析,GO法更能反映出系统的原貌。引信系统具有多态有时序的特点,为了减少应用故障树分析其可靠性时的工作量,应用GO法对某弹底机械触发引信系统的可靠性进行了分析,建立了完整的GO图,计算出了系统的可靠度。结果表明:应用GO法得到的引信系统可靠性分析结果与采用故障树分析法得到引信系统可靠性分析结果基本一致,而运用GO法分析的工作量却大大少于故障树分析法,GO法分析引信系统的可靠性也比较方便。

GO Methodology is a method of the system reliability analysis. It＇s a success-oriented system reliability analysis technique. Comparied with FTA（failture tree analysis）, in some special systems, especially in following system and sequence system, it can reflect the essence of the system more distinctly. In order to reduce the work by FTA, the reliability of the fuze system is analyzed by the GO Methodology. The GO chart is integratively protracted and the system reliability is quantified. The result by the two methods is consistent basically, but the work by GO Methodology is much fewer than FTA. It indicates that the fuze system reliability analysis by the GO Methodology is very convenient and proper.
