| 摘 要： | 通过分析液压轮边制动系统原理,以故障模式为底事件建造液压轮边制动系统T-S故障树。针对实际系统故障数据缺乏、故障机理复杂多样等原因导致的T-S故障树底事件失效可能性的不确定性问题,将区间模型引入T-S故障树分析,解决底事件失效可能性不易精确获取的问题;进而对系统进行可靠性分析,求得液压轮边制动系统故障树顶事件的故障概率、各底事件的概率重要度和关键重要度,为系统维护和故障发现提供依据。

| Abstract: | By analyzing principle of hydraulic wheel braking system, we establish a T-S fault tree of hydraulic wheel braking system based on fault mode. In order to solve the uncertainty of basic events failure possibilities in actual system due to poor fault data and complex fault mechanisms, an interval model is introduced into the T-S fault tree analysis. The failure probability of the top event and the probability importance degree and critical importance degree of each basic event can be obtained by analysis. It provides a theoretical basis for system maintenance and fault finding. |
