长寿命航天器机构的加速寿命试验方法

Methods of Accelerated Life Tests for Long-life Spacecraft Mechanisms

介绍了加速寿命试验的概念、类型和基本特征;综述了长寿命航天器机构加速寿命试验方法的研究现状;分析了固体润滑和油润滑长寿命航天器机构准加速寿命试验方法的特点;针对目前长寿命航天器机构准加速寿命试验中存在的问题,提出了解决这些问题的思路。

The basic concept, types and features of accelerated life tests were introduced. The methods of accelerated life tests for long-life spacecraft mechanisms, both in China and abroad, were reviewed. The characteristics of methods of accelerated life tests for both solid-lubricated and oil-lubricated long-life spacecraft mechanisms were analyzed. Solutions to some problems existed in quasi accelerated life tests for long-life spacecraft mechanisms were put forward.
