摘　　要：通过对鱼雷典型动力系统的功能结构和故障判据进行分析,建立了鱼雷动力系统故障树,在故障率为模糊数的模糊故障树可靠性分析方法的基础上,应用模糊数学理论对其进行了模糊故障分析,并应用模糊重要度分析的中值法对重要度进行了计算,取得了很好的效果,为鱼雷系统可靠性分析提供了新的途径。Based on the analysis of typical torpedo dynamic systemic function , structure and fault criterion, a fuzzy fault tree is established. Used an fuzzy mathematics method of reliability analysis with fuzzy fault rate and the median method of fuzzy significance analysis, the fuzzy fault rate and fuzzy significance of parts and subsystem is calculated. Results listed in table one and table two.According to the results the measures to improve the reliability of torpedo dynamic system are pointed out.
