为了更有效地解决飞机弹射救生座椅可靠性评估的问题,考虑飞机弹射救生座椅子系统试验数据与系统试验数据之间既有联系又有区别的特点,采用继承因子描述这两种试验数据之间的相似性,建立了一种基于继承因子的飞机弹射救生座椅Bayes可靠性评估方法。采用该方法对某型飞机弹射救生座椅可靠性进行了评估,在置信度90%的情况下其可靠度下限达到了0.954。结果表明,在相同的系统级试验样本量情况下,评估结果比经典统计方法更合理。 In order to solve the problem of reliability assessment of the plane’s life-saving seat more effectively, considering both the existing and the difference between the test data of the plane’s life-saving seat system and the system test data, the inheritance factors are used to describe these two kinds of test data A bayesian reliability assessment method based on the inheritance factor was established for the aircraft ejection rescue seat. This method is used to evaluate the reliability of a certain type of aircraft’s life-saving seat, and its reliability is 0.954 under 90% confidence level. The results show that the evaluation results are more reasonable than the classical statistical methods under the same system-level experimental sample size.
