基于GJB899A的可靠性统计试验方案分析

Analysis of Reliability Statistical Test Scheme Based on GJB899A

摘要:

可靠性试验作为可靠性工程的重要一环，是衡量产品是否满足可靠性要求的重要手段之一。 GJB899A《可靠性鉴定和验收试验》给出了一系列统计试验方案，主要涉及定时截尾试验方案和序贯截尾试验方案。针对这 2 类试验方案的原理开展分析，根据试验方案的所需参数明确方案的确定方法，给出可靠性指标的验证方式。结合应用示例进行了分析说明，用以指导工程人员根据被试产品的可靠性要求选择合适的可靠性试验方案，可以有效帮助研制方和订购方开展可靠性试验。

Abstract:

As an important part of reliability engineering，reliability test is one of the important means to measure whether products meet the reliability requirements. GJB899A "Reliability Appraisal and Acceptance Test" standard gives a series of statistical test schemes，which mainly involve the fix-time censored test scheme and the sequential censored test scheme. In this paper，the principles of these two types of test schemes are analyzed，the determination methods of the test schemes are defined according to the required parameters of the test schemes，and the verification method of reliability indexes is given. Combined with application examples，it is analyzed and explained for guiding engineers to choose the appropriate reliability test scheme according to the reliability requirements of the tested products，which can effectively help developers and orderers to carry out reliability tests.
