摘要
将灰色预测模型应用于航空发动机滑油光谱分析技术中,对滑油中铁元素浓度值进行了拟合和预测,并且针对及时地进行故障预测的需要,提出了缩短预测期后的一步预测值的确定方法。应用结果表明,本方法是可靠的。
Grey predicting model was applied to lubricating oil spectrometric analysis of aero-engine. Based on this model the concentration value of iron element in lubricating oil was simulated and forecasted. Arid to predict fault in time, a way was presented which can predict one-step data after shortening predicting time. The obtained results show that the method is reliable.
