摘　　要：本文讨论了机械产品单元的Bayes可靠性评估问题。当应力强度均服从正态分布，且分布参数未知的情况下，分析机械产品单元的可靠性评估问题，得出应力-强度模型可靠性的近似分布，讨论给出了无验前信息时的可靠性Bayes精确下限。In the paper, Bayesian reliability evaluation of the mechanical component is discussed. The reliability evaluation of mechanical component is analyzed when the stress and strength are independent and follow normal distribution. The components reliability lower bounds of a stress-strength model is obtained and its approximate distribution of the reliability is given. Besides ,accurate Bayesian lower bounds of reliability are given when none of prior information is available,
