| 针对高空舱舱盖机构系统故障源与故障程度难以判定以及故障特征值难以提取的问题，提出了基于T-S 模糊故障树分
析与仿真相结合的故障诊断方法。将T-S模型引入到舱盖机构不同步的典型故障分析中，用模糊可能性描述部件的故障概率；用
T-S门来描述事件间的联系；用模糊数描述部件的故障程度，结合模型仿真模拟故障分析，获取部件发生故障时对顶事件的贡献或
重要度，计算出顶事件发生故障的模糊可能性及其诊断决策。为高空舱舱盖机构的故障诊断和维修保养提供参考。 |

| According to the problem of difficult to determin fault source and foult degree and difficult to obtain fault characteristic
value of high-altitude simulation test chamber cover mechanism system, a fault diagnosis method of chamber cover mechanism system based
on T-S fuzzy fault tree analysis and fault simulation was proposed. T-S model was presented to typical fault analysis unsynchronized for
chamber cover mechanism, which fault probabilities were described as fuzzy possibilities, events' relationships were described by T-S gates,
and fault degrees were described as fuzzy numbers. The fault were simulated in the failure mode, which the fault contribution to top event
were achieved, as well as fuzzy fault possibilities of top event and comprehensive decision were achieved. It provides reference for the
troubleshooting and maintenance of high-altitude simulation test chamber cover mechanism |
