摘要
目前,大多数评估方法没有考虑失效数据的删失性。对于弹药这种不维修产品,尤其是在贮存中何时失效,目前尚无法检测,因此通过考虑弹药贮存试验数据的删失性的可靠性评估方法,可以得到更加合理的评估结果。本文分析了弹药贮存数据的特点,介绍了删失数据的类型及其对应的似然函数,讨论了弹药贮存的三种不同寿命分布函数的似然方程,提出了无寿终数据和有寿终数据的估计方法,并分别通过实例进行了评估。
Most of the assessment methods used for ammunition storage reliability do not take into account the censoring of data.As a kind of product without maintenance,there is no way of perdicting when an item of ammunition will be fail.With a method of assessment taking into account the censoring of data,more reasonable conclusions about ammunition storage reliability can be obtained.In this paper,properties of ammunition storage data and their model of censoring are discussed.Three kinds of different life distribution function are here dealt with.Two Kinds of assessment methods for endless-life and limited life data respectively are advanced.The methods which are used in practical product assessment are discussed.
