| 摘 要： | 本文运用逻辑诊断和故障树分析法对300台柴油机的运转状态进行分析,建立柴油机运转危险状态故障树模型,求出在目前水平下危险状态发生的概率为0.000288;定量地指出故障树模型的结构重要度、概率重要度,提出要改进调速器的设计、制造和安装质量以减少其失效发生的概率;通过关键性重要度计算及其对比,寻找出喷油泵维修、调试及保养不当是引起危险状态发生的第一个关键性事件,并确定其他故障的作用。

| Abstract: | By logical diagnosis and fault tree analysis, the operational condition of 300 diesel engines was analysed and a fault tree model of diesel engines under hazard condition was established. The occurence probability of hazard condition at the current level was determined to be 0.000288. Structural importance and probable importance of the model were proPosed statistically and qualitical improvements of governor design, manufacture and installation were suggested to reduce inefficiency occurence probability. Through calculation and comParison of crucial importances, the key importance for risk condition occurence was ascertained to be improper maintenance, adjustmemt and service of fuel injection PumP. The effects of other failures were determined. |
