可靠性高加速试验技术及其在我国空间站应用领域实施的总体思路

Highly Accelerated Reliability Testing and Thoughts of Its Implementation on China Manned Space Station

我国载人空间站任务计划运营周期10年以上,期间开展长期、持续的空间科学与应用研究,对应用有效载荷提出了"长寿命、低成本"的任务需求,需要采用高加速试验技术(HALT、HASS)提高并评估航天产品的可靠性。早期的高加速试验多用于民用产品,且多采用定性方法。近年来高加速试验的研究取得持续进展,逐渐注重HALT、HASS的定量研究。本文结合我国空间站应用领域"长寿命、低成本"的任务需求,提出了HALT-HASS-ADT(HHA)的高加速试验集成方法及其总体实施思路。

China manned space station will operate for over ten years. Long term and sustained space science and application researches will be conducted during its operation. So the application payloads must meet the ＂long life and low cost＂ mission requirement. Thus highly accelerated tes-ting （ including HALT and HASS ） is needed to improve and estimate the reliability of the space products. Early highly accelerated testing is commonly used in the civilian products and often with qualitative methods. In recent years, the research on highly accelerated testing has made consistent progress, and quantitative study of HALT and HASS is emphasized. According to the＂long life and low cost＂ mission requirement in the space station application field, a HHA accelerated testing method was proposed in this paper by the integration of HALT, HASS and ADT. In addition, the o-verall implementation of HHA accelerated testing method was also proposed.
