摘要:

恒应力加速寿命试验是快速获得电子元器件失效数据、测量其寿命的有效方法.将该方法用于环形腔He-Ne激光器产品,根据环形腔激光器失效概率试验数据的分布特征,提出了一种先验分布函数,并由加速寿命方程出发,导出了计算环形腔激光器特征寿命的公式.对环形腔激光器产品试验数据进行了处理,精确地估算出环行激光器产品的寿命,极大地缩短了试验周期.

关键词: 加速寿命试验, 先验分布, He-Ne激光器, 环形腔激光器

Abstract:

Constant-stress accelerated Life test is a rapid and effective method for obtaining the failure data and making life prediction of the electric component. This paper first applies this method for the He-Ne ring laser. A new prior distribution function based on the distribution of the life test data of the He-Ne ring laser is introduced. According to accelerated life equations, formulation of life prediction of the He-Ne ring laser is obtained and test data of the He-Ne ring laser are also analyzed.This method which was proved by experimentation not only precisely estimates the life of the He-Ne ring laser, but also considerablely shortens the test cyclebut.

Key words: accelerated life testing, prior distribution, He-Ne laser, ring laser
