The invention discloses a method for verifying an aircraft landing gear recovery interval. The method comprises the steps of collecting operation data, determining a group where an aircraft landing gear is located, and screening out the operation data of each group of aircrafts in a key operation environment. Then, based on the occurrence frequency of the important faults of each group of aircraft landing gears, determining samples according to an error and a confidence coefficient between the occurrence probability of the important faults in a single sampling process and the occurrence probability of the important faults in actual operation; then, the corrosion and wear conditions of key components in the sample are checked, and the number of important faults in the actual undercarriage sampling process is obtained; when the probability that the number of the important faults is smaller than the expected number in the actual undercarriage sampling process reaches the preset confidence coefficient, it is judged that the aircraft undercarriage recovery interval is reasonable. Through the method, not only can the rationality of the recovery interval of the aircraft landing gear be effectively judged, but also the occurrence trend of important faults of the aircraft landing gear can be analyzed and predicted.
本发明公开了一种用于验证飞机起落架恢复间隔的方法。该方法包括收集运行数据,确定飞机起落架所在组,再筛选出在关键运行环境下每组飞机的运行数据。然后,基于每组飞机起落架的重要故障发生次数,根据单次抽样过程中重要故障发生的概率与实际运行中重要故障发生的概率之间的误差和置信度确定样本。随后,检查样本中关键部件的腐蚀和磨损状况,获得实际起落架抽样过程中重要故障数量。当实际起落架抽样过程中重要故障数量比预期的数量少的概率达到预定置信度时,则判定为所述飞机起落架恢复间隔合理。通过该方法不仅能够有效判定飞机起落架恢复间隔的合理性,还能够分析预测飞机起落架的重要故障发生的趋势。
