摘　　要：研究了降落伞系统的可靠性综合评估方法;给出了基于应力强度模型,利用强度试验数据,运用信仰统计推断法计算降落伞组件可靠度置信下限的方法,并对该方法与渐近正态法、分位数修正法进行了对比分析。分析表明,就精确度而言,基于信仰统计推断法给出的评估结果较好。In this paper, the integrating evaluation method of parachute system reliability was presented. Then, the confident limit of parachute component reliability was computed by means of the fiducial inference based on the stress - strength model and the strength test data of parachute. The Comparison analysis was given for three methods. The analysis result showed that the evaluation result based on fiducial inference was more accurate than the other two methods.
