| Abstract: | Applying the method of fault tree analysis(FTA)to analyze the faults of engine cooling system overheat of a vehicle,all kinds of possible reasons and their combined forms of cooling system overheat have been found out,and qualitative analysis and quantitative calculation have also been made.Based on the minimal cut sets got by fault tree qualitative analysis,it is convenient and quick to find the bottom event faults that led to top event,and the direct and effective measures can be taken to prevent engine cooling system overheat faults or greatly reduce its occurrence probability. |
