Mechanical Failure Analysis of Aircraft Alternator Based on Fault Tree and Case Reasoning

Abstract:

Aircraft alternator is in the central position of the aircraft AC power system. The existing troubleshooting process is complex and tedious. In this paper, the aircraft alternator fault tree is established, and a fault example of under-voltage condition is analyzed in-depth qualitative and quantitative. According to the importance degree, the order of troubleshooting is obtained, making the fault diagnosis fast and effective. In order to overcome the limitation of the fault tree analysis, case-based reasoning is combined, making the fault diagnosis more comprehensive and accurate.
