摘要

摘要: 润滑脂老化性能退化对航天器展开机构、运动部件等运行的可靠性至关重要，但目前针对润滑脂的老化对性能影响及寿命预测的研究相对较少，缺少系统的理论指导航天器长寿命润滑脂的应用.选取质量变化率作为老化失效关键指标，通过应用阿伦尼乌斯方程（Arrhenius equation）和时间温度关系，得到一个基于润滑脂质量保留率的时间温度等效模型，可预测润滑脂在各种贮存条件下的质量变化.通过监测滴点、锥入度等关键性能指标的变化来评估其老化性能.研究表明，老化对滴点、锥入度性能影响较大，当润滑脂质量损失率达到1%时，预测失效寿命为5.4 a.同时，利用四球摩擦试验研究了润滑脂在不同载荷下对轴承钢GCr15的摩擦性能.结果表明，在较大载荷条件下，老化对润滑脂摩擦因数与磨斑直径的影响更加显著.研究结果及方法为了解润滑脂老化性能退化及寿命预测研究提供了依据，能够为航天器长寿命润滑脂的选择和优化设计提供理论支撑.

Abstract: The lubricating grease degradation and aging performance is critical to the reliability of spacecraft deployment mechanisms, moving components, and other related products. Limited research has been conducted on the effects of grease aging on performance and lifespan prediction, with insufficient theoretical support for the application of long-life lubricating grease in spacecraft. The quality change rate was selected as the key performance for aging failure, a time temperature equivalent model based on the quality retention rate of lubricating grease was obtained by means of the Arrhenius equation and the time temperature relationship, which can predict the quality change of lubricating grease under various storage conditions. Key parameters such as the droplet point and the cone penetration were monitored to evaluate the lubricating grease aging performance. The results show that, aging has a significant impact on the droplet point and the cone penetration performance, with a 1% loss rate of the lubricating grease mass indicating a predicted lifespan of 5.4 a at the failure point. In addition, a 4-ball friction test was used to study the lubricating grease friction performance on bearing steel GCr15 under different loads. The test indicate that aging significantly influences the lubricating grease friction coefficient and the wear zone diameter under high loads. The research results and methods provide a basis for understanding the lubricating grease degradation and aging performance, and predicting its lifespan.
