摘　　要：为了对机械密封的寿命进行可靠性评定,文中在其寿命服从两参数威布尔分布时,基于无失效数据的最优置信限法给出了可靠性参数—可靠度、可靠寿命的置信限,并分析了影响其估计值的主要因素。For the reliability evaluation of mechanical seal, this paper gives the conifdence limits of reliability parameters-reliability and reliability life.The conifdence limits are oriented tothe products of which life is subordinate to Weibull distribution and computed based on optimal conifdence limit method.Main factors affecting the estimations are also investigated.

关 键 词：可靠性 无失效数据 威布尔分布 置信限
