摘要
针对高价值弹药引信利用全弹飞行试验验证其可靠性成本过高的问题,提出用卡方拟合优度法确定继承因子。以混合Beta分布为先验分布,得到了评估引信可靠性的Bayes方法,该法解决了模拟试验数据与靶试数据融合问题。以国外某引信为应用背景进行了可靠性评估,证明该法比经典方法减少1/3的靶场试验量。
In view of the high cost for verifying the reliability of high-valued ammunition fuzes with complete-round flight test,it is proposed to determine inheritance factor by chi-square goodness-of-fit.A Bayes method of reliability evaluation for fuzes is put forward based on mixed beta distribution as the prior distribution,which solves the problem of data fusion between simulation and field test.Reliability of a certain foreign fuze is estimated with the given method,showing that the specimens using in the field test are one-third fewer than the specimens with the typical method.
