| 摘 要： | 可靠性数据是故障统计历史信息的记录,数据内隐含着大量对维修人员排故具有指导意义的信息,为达到提高工作效率,减少排故时间,以保证航班正点运营的目的,提出将可靠性数据应用于民机故障诊断的计算模型。利用从可靠性报表中收集到的数据对某航空公司主力机型A320-200飞机的空调系统常发故障进行诊断,首先用粗糙集(RS)对8个可能导致温度控制组件超温故障的部件进行分析,初步总结出3个故障源,然后计算综合故障概率,最后用Weibull分布验证以上诊断结论。结果表明,该法的引入能实现故障源的精确定位,并在实际中成功排故,大大缩短维修时间。

| Abstract: | Reliability data are statistical record of the history failure,which imply a large amount of information guiding the troubleshooting for the maintenance.In order to improve the efficiency,reduce the time of troubleshooting and ensure the flight on schedule,a calculation model based on reliability data for fault diagnosis of civil aircraft was proposed.The data collected from the reliability report were applied to diagnose the permanent fault of air-conditioning system for A320-200 aircraft of an airline,and... |
