摘　　要：潜通路分析方法是可靠性分析中一种常用的方法,是减少设计问题,提升可靠性的一种重要手段。当前的潜通路分析方法主要是应用于电路系统分析,也有部分包含管路系统的应用,但是还没有适用于复杂系统的潜通路分析方法。针对上述问题,提出了一种基于图论的系统潜通路分析方法,首先构建基于流的系统模型,然后将模型中不影响分析的连接关系及模型节点简化,最后将系统模型转换为抽象的图模型,并利用节点识别和路径追踪的方法进行分析。最后,将所提方法应用于直升机起落架误收问题的分析,证明了所提方法的有效性。Sneak analysis is a commonly used approach in reliability analysis,serving as an important means to reduce design issues and enhance reliability.The current sneak analysis methods are mainly applied in circuit system,with some applications in pipeline systems.However,there is still a lack of sneak analysis methods suitable for complex systems.To address the above problems,this paper proposes a sneak analysis method for systems based on graph theory,which first constructs a flow-based system model,then simplifies the relations and nodes in the model that do not affect the analysis,and finally converts the system model into an abstract graph model and analyzes it by using node identification and path tracing methods.At the end of this paper,the proposed method is applied to the analysis of the helicopter landing gear mis-acceptance problem,which proves the effectiveness of the proposed method.
