摘　　要：根据某大型轰炸机液压系统统计资料的153个液压刹车胶囊有效样本,应用三参数威布尔分布对该故障部件进行了可靠性数据处理和寿命评估分析,对比以往在工程上采用两参数威布尔分布分析航空装备构件可靠性寿命的结果。分析表明,采用三参数威布尔分布分析和评估所得结果与实际使用情况吻合度更高。According to the statistics of 153 hydraulic brake capsule effective samples about a large bombers hydraulic system,we used three-parameter weibull distribution for reliability data processing and life assessment analysis on the fault component, and contrasted the past results on the engineering analysing of the reliability life of the aviation equipment component based on two-parameters weibull distribution,and the result of using three-parameters weibull distribution analysis and evaluation has higher fitness with the actual usage.
