  • 摘要:

    导电滑环作为卫星太阳电池矩阵驱动机构的核心部件,其可靠性关系到卫星寿命的长短,由于空间用滑环寿命试验费用昂贵、试验周期长、样本数据量少等特点,无法获取大样本寿命数据,利用传统大样本数据进行统计推断,从而进行可靠性评估的方法存在困难。因此提出一种基于摩擦磨损模型的可靠性评估方法,应用赫兹理论、传热学方法分别计算摩擦副磨损过程中的接触区域变化和温度变化,量化热力电多场耦合对摩擦副磨损的影响,提出基于粘着磨损的多物理场耦合磨损模型,基于该模型得到的寿命数据,运用改进Bootstrap方法得到滑环寿命分布的参数估计,最后与传统可靠性预测方法结合,得到一系列滑环可靠性指标。方法对比结果表明,改进Bootstrap方法不仅具有较高的评估精度,还具有主观性小、适用性强的特点,由该方法所得的各可靠性指标均符合工程实际,具有很强的工程应用价值。
