Abstract:

本发明公开了一种基于最大熵试验法的小样本产品可靠性验证方法,包括步骤:1)确定产品载荷或承载能力的均值μ和均方差σ,确定合适的载荷强化系数K;2)根据产品可靠性要求R和置信度要求γ,利用试验所需样本量计算公式计算试验所需样本量N;3)对N个样本进行成败型试验;4)验证产品可靠性。本发明通过加大样本载荷或减少样本承载能力,使单个样本所含的试验熵尽可能大,而达到用小样本验证产品高可靠性、高置信度水平的目的。与经典方法和贝叶斯方法相比,本发明具有试验所需样本量少、试验效率高的优点,特别是对高可靠性、高置信度要求的产品进行可靠性试验时,本发明的优势更为明显,具有广泛的工程应用价值。
