摘　　要：针对在长寿命高可靠产品的样本及数据极少的情况下,同一个样本由于经历了不同环境下的试验而无法进行寿命及可靠性评估的问题,通过对产品进行可靠性建模,并在此基础上进行失效率预计,由预计结果计算获取了各种试验环境下的环境折合因子,由此得到不同环境下的试验所对应规定环境下的试验信息,可对产品的寿命及可靠性进行评估。Aiming at the service life and reliability evaluation problems of long life and high reliability products,which are rare samples and data,and samples experiencing different environmental tests,an integrated reliability evaluation method was put forward.Through building the product reliability model,product failure rate was predicted.The result was used to calculate the environment converting factor for diffident environmental tests.Test information of regulated environment was obtained from different environmental test and service life and reliability evaluation of product can be made at last.

关 键 词：多试验信息 环境折合因子 可靠性评估
