采用工程界普遍使用的AMSAA模型,对某型弹上电子设备进行了可靠性增长试验,达到了预期的可靠性增长目标,验证了AMSAA模型方法的合理性,并简述了一种在AMSAA模型基础上采用牛顿迭代法来预测特定MTBF下的试验时间的方法,该方法合理可行,对开展可靠性增长与可靠性增长试验工作具有重要的实际意义。 The AMSAA model, which is widely used in engineering, was used to test the reliability growth of a type of projectile electronic equipment. The target of reliability growth was achieved. The rationality of the AMSAA model method was verified. Based on the use of Newton’s iterative method to predict the test time under a specific MTBF method, this method is reasonable and feasible, and has important practical significance for the pilot work on reliability growth and reliability growth.
