| 摘 要： | 针对可靠性强化试验难以定量计算产品可靠性指标的问题,采用应力强度模型和数理统计理论,提出一种通过强化试验数据计算产品外场可靠度的工程适用方法。在对某基于ARM微处理器的嵌入式系统进行可靠性强化试验的基础上,采用该方法计算出产品在振动环境条件下的外场可靠度。提出的方法能够对改进产品可靠性起指导作用。

| Abstract: | Reliability Enhancement Test(RET) can not directly produce a meaningful reliability parameter through the test results due to the limitation of its methodology. This paper develops an engineering suitable approach for evaluating the reliability of the outfield products,which adopts the vibration stress-strength model and the theoretical statistic approach.On the basis of the RET results of a set of ARM micro processor based embedded system,the reliability of the system in the field vibration environment is calculated by means of the derived method,which proves that the approach can be a guidance to improve the reliability of products. |
