| 摘 要： | 针对复杂的航空发动机系统,提出一种基于因果图的方法对其进行安全性分析。以微小型涡喷发动机机匣破裂或被击穿失效为例,对因果图在安全性分析中的应用进行了研究,并与传统的故障树分析结果进行了对比和分析。研究结果表明,基于因果图的方法一方面可以找出导致航空发动机系统失效的原因之间的复杂因果关系,给出定量分析,符合客观实际;另一方面图形化的推理方法易于安全评估和工程应用。

| Abstract: | An improved safety analysis based on the causality diagram for the complex system of micro aero-engines is presented.The study is examined by using the causality diagram in analytical failure cases due to rupture or pentration in the receiver of micro turbojet engine casing,and the comparisons are also made with the results from the traditional fault tree analysis.Experimental results show two main advantages:(1)Quantitative analysis which is more reliable for the failure analysis in jet engines can be prod... |
