摘　　要：为确保安全、可靠运行,需对系统的薄弱环节或脆弱节点开展分析,将安全科学工程中脆弱性概念引至船舶蒸汽动力系统网络领域,在分析船舶蒸汽动力系统网络特点的基础上,创建和蒸汽动力系统网络匹配的脆弱性模型,利用船舶工程评估经验,提出脆弱性的量化计算方法。结合某船蒸汽动力系统网络实例,进行蒸汽动力系统网络脆弱度的计算,并将计算结果与该船实际故障样本进行对比分析,两者基本一致。通过实例计算,验证创建的动力系统网络脆弱性模型合理、有效,表明动力系统网络脆弱性计算方法正确、快速。In order to ensure the safe and reliable operation,it is necessary to carry out research on the weak links or vulnerable nodes of the ship’s steam power system.The concept of vulnerability in safety science and engineering was introduced to the field of ship steam power system network.Based on the analysis of the characteristics of ship steam power system network,a vulnerability model matching with the steam power system network was established,and a quantitative calculation method of vulnerability was proposed based on the experience of ship engineering evaluation.Taking a steam power system network as example,its fragility was calculated compared with the actual fault samples of the ship,finding that they are basically consistent.It was verified that the network vulnerability model of dynamical system created is reasonable and effective,and the proposed calculation method is correct and fast.
