摘　　要：为了减少因分布模型选择不当而造成分析误差,提出基于非参数统计的飞机部件使用可靠性分析方法,采用KaplanMeier完成可靠度计算及置信区间估计。基于分析得到的自由寿命数据进一步得出该部件可靠性寿命模型,综合使用KS检验及相关系数法确定样本数据总体分布的最佳拟合函数,并选择非线性秩回归(NLRR)进行分布函数进行参数估计,确定可靠性特征量。随后对各特征量随时间变化趋势图进行分析,寻找系统可靠性参数的演变规律,为基于MSG-3维修思想的维修时间间隔调整提供必要的理论依据。In order to reduce analysis errors caused byincorrect distribution model selection, operationalreliability analysis method for aircrqf＇components is proposed based on the non-parametric statistical method, using Kaplan-Meier to do reliability calculation and confidence interval estimation. In order to further that the component reliability life model, based on the free-life data from the non-parametric analysisand integrated use of K-S test and correlation coeffwient method, the best fitting function for overall distribution of sample data is decided. Nonlinear rank regression （NLRR） model is used far estimating distribution parameter aud reliability characteristic quantity. By aualyzingthe trend graphs of characteristic quantity, the theory and methods of establishing predicted maintenance scheme based on MSG-3 for the aircraft componentsareproposed.
