试验室可靠性试验与现场使用结果不一致性研究

Research on Inconsistency between Laboratory Reliability Test and Field Usage Results

本文论述了当今试验室可靠性试验与使用使用结果不一致的情况,指出在许多情况下实验室可靠性试验得出的MTBF值在现场使用统计中为实验室的一半左右,导致不一致的原因有许多,例如实验室试验大都选用高风险率的方案,当今实验室的可靠性大都硬件的可靠性试验,没有同时运行软件等,为此本文提出了缩短差距的方法和措施。

This paper discusses the inconsistency between laboratory reliability test and field usage results,and points out that in many cases,the MTBF value obtained from laboratory reliability test is about half of that in the field usage statistics.There are many reasons for the inconsistency,such as the use of high-risk rate schemes in most laboratory tests,and the lack of software operation during the use of hardware in most of the reliability tests today.Hence,this paper proposes some methods and measures to shorten the gap.
