【摘要】 在充分研究航空救生工程系统可靠性评估现状,比较各种现行可靠性评估方法的基础上,建立了一种适用于研究小样本、高可靠性成败型的航空救生工程系统的贝叶斯可靠性评估方法。将其应用到某型航空救生工程系统的设计定型中,评估结果达到规定的可靠性指标只需要13次试验,而若用其他的方法达到同样的可靠性指标则需要进行46次试验。由此证明,该可靠性评估方法具有重要的实用价值。更多还原

【Abstract】 The Bayes reliability evaluation method was established,which is fit for evaluating the reliability of the aircrew escape system characterized by small number of samples and high reliability pass-failure type.Although only 13 tests were done on certain-type rocket ejection seat for its design finalization,the evaluated results have reached the reliability indexes stipulated in the national standards by means of the proposed Bayes reliability evaluation method.However if other methods were used,a total of 46 tests would be needed in order to reach the same reliability indexes.The research is of great practical value.更多还原
