| 摘 要： | 共模故障是一种相依失效事件，该事件的存在增加了复杂系统的联合失效概率，降低了冗余系统的可靠度，给系统设备带来了巨大的安全隐患。论述了共模故障的基本概念，分析了产生共模故障的原因，给出了共模故障定性分析过程，分别提出了基于扩展故障树和马尔柯夫分析的共模故障失效概率计算方法，在安全性分析领域进行了有益的探索。

| Abstract: | Common mode failure(CMF) is dependent failure event,which increases joint failure probability of complex systems and reduces the reliability of redundant systems so that CMF causes huge security risks to the systems.According to the basic concept of CMF,the causes of CMF are analyzed and the qualitative analysis process is given for the CMF.Based on extend fault tree and Markov analysis,the probability calculation methods of CMF are put forward. |
