摘　　要：文章首先从飞机安全性及经济性的角度提出了针对A321飞机胎压指示系统旋转机构可靠性分析的必要性,并对该部件系统原理及故障现象进行了简述。基于维修现场的失效数据,使用可靠性分析软件WEIBULL++完成标准化尺度评价点的拟合率计算,从而确定样本数据总体分布类型。随后利用非线性秩回归(NLRR)方法估算出寿命分布函数的相关参数及特征方程,通过平均故障间隔时间与实际拆换情况的对比,为维修决策提供必要的理论依据。Firstly, the necessity of the reliability analysis for A321 TPIS Rotating Mechanism is put forward from the perspectives of economic efficiency and flight safety and the system philosophy and malfunction is briefly described. Based on failure data at maintenance site collection, distribution pattern of sample points is estimated with correlation coefficient（PLOT） test by WEIBULL＋＋. Then,Nonlinear Rank Regression（NLRR） method is used to estimate the relevant parameters, and the characteristic equation of life distribution function and component’s reliability analysis is completed.Finally, the contrast between the MTBF and actual replacement data provides the necessary theoretical basis for maintenance decision-making.
