摘要
针对火箭助飞鱼雷装载可靠度试验试验样本量少、周期短的问题,提出了补充验前信息以进行考核,考虑到验前信息可信度。然后将鱼雷装载可靠度指标转化为指数分布下的平均寿命指标,获得参数的验后分布,推出基于指数分布的Bayes融合评估方法。仿真算例表明:方法可行,能够较可信地评估出火箭助飞鱼雷装载可靠度指标值。
Aiming at small test samples and test time of the rocket-assisted torpedo＇s loading reliability,the supplement of prior information considering credibility is proposed.Torpedo＇s loading reliability is converted to mean life based on exponential distribution,so posterior distribution is got.The bayesian fusion and estimation for torpedo＇s is proposed.The feasibility and creditability of the proposed method is demonstrated with a simulation example.
