加速寿命试验技术综述

A COMPREHENSIVE REVIEW OF ACCELERATED LIFE TESTING

加速寿命试验是可靠性试验技术一个重要的分支 ,相关的研究受到了统计学界与可靠性工程界的广泛关注。本文对加速寿命试验领域的相关理论研究与工程实践作了阶段性的总结 ,对下一步的研究具有一定的启发意义。文中首先介绍了加速寿命试验的有关概念 ,接下来分恒定应力试验的统计分析、步进应力试验的统计分析、序进应力试验的统计分析以及加速寿命试验的优化设计 4个专题对加速寿命试验的相关研究进行了概述 ,然后简要回顾了加速寿命试验在我国的工程应用情况 。

Accelerated life testing (ALT) is an important branch in reliability testing and is a focus of research both for statisticians and reliability engineers. The paper outlines the four topics of study embodied in ALT,viz.: statistical analysis for constant-stress testing, step-stress testing and progressive stress testing, and optimal design for ALT. It gives a general review of engineering applications of ALT in China, and points out some possible directions in ALT, giving some suggestions for further study.
