摘要
采用了工程界普遍使用的AMSAA模型 ,充分利用了同类或相似产品研制试验故障数据 ,对于研制试验中含较多试验项目的情形将其归结为几种典型的环境应力类型 ,提出了一种通过最优化过程确定时间环境折合系数的方法 ,最后给出了研制阶段MTBF(MeanTimeBetweenFailures)置信区间的求解方法 .研究结果表明 ,该方法合理可行 。
Based upon the AMSAA model which has been widely used in engineering,a method of defining the time environmental conversion factor was proposed through optimization process, which made full use of the failure data from the same kind of products or the similar products in their development tests, and it made all the development test items into a few typical environment stress types in case the development test include more items, at last a method of defining the MTBF(mean time between failures) confidence interval values of the product in its development stage was given. The research result indicates the method is reasonable and feasible, it can satisfy the precision requirement in engineering.
