摘要: 用数字仿真法,对工程经验法进行理论分析,建立了寿命试验中所需的参数:样本量n、可靠性r%、显著性水平与各经验系数K_i之间的量化关系,从而为各经验系数K_i的确定与选取提供理论依据,以满足厂内寿命试验方案设计或评定产品首翻期的有关要求。

Abstract: This paper uses numerical simulation method to analyze 'Engi-neering Experience Method' theoretically. It establishes the quantified relationship between the experience factors and the required life test parameters such as sample size n, reliability r%, significance levels.So as to provide theoretical basis for determining or selecting experience factor K and to satisfy the related requirements for designing the lift test plan or evaluating the overhaul time of products.
