| 摘 要： | 对于比较贵重、寿命很长及检查项目较多的航空、航天电器产品 ,在进行可靠性试验时 ,通常会出现无失效数据 ,应用经典方法估计其可靠性特征量会引入较大误差。提出采用不定时检查的方法对其进行可靠性试验 ,并应用Bayes理论对试验中可能出现无失效数据时的可靠性特征量进行了估计。

| Abstract: | Zero-failure data is always obtained from reliability test for the long life electrical apparatus used in aeronautics industry. A large error is introduced in the estimation of reliability characteristic parameter when the classical estimation method is used. Bayes estimation method has been put forward in this paper. This data processing method can be used to estimate the reliability characteristic parameter in case of the failure data obtained from reliability test is the zero-failure data. |
