摘　　要：利用弹射弹单元试验数据和全弹鉴定试验数据,应用多层Bayes可靠性评估方法对某弹射弹的可靠性进行了估计,评估结果为该弹射弹的可靠性达到了0.996。结果表明,采用该方法是有效的,比GJB376中规定的计数法要极大地降低全弹试验量。The reliability of a cartridge of ejector is estimated by hierarchical Bayes reliability estimation method,based on whole cartridge of ejector test data and its unit test data. The reliability of the cartridge of ejector is reach 0.996 and the estimation result shows the method is effective and the required test number is less than that by attributes method in GJB376.
