A Calculation and Prediction Method of Lubricating Oil Consumption Rates for Aeroengines
针对航空发动机滑油箱油量测量值易受多个参数影响导致滑油消耗率难以计算和预测的问题,提出了一种改进的滑油量数据提取规则和滑油消耗率预测方法.基于密度聚类算法(Density-based spatial clustering of applications with noise,DBSCAN)等方法对发动机数据进行了清洗,获取平稳飞行状态下滑油量数据.使用最小二乘法对滑油量进行拟合,得到了滑油消耗率,平均拟合优度达到了 0.86.在此基础上,利用多层…查看全部>>
Since the measurement of oil quantity in aviation engine lubrication systems is susceptible to multiple parameters,it is difficult to calculate and predict oil consumption rates.We propose an improved method for extracting oil quantity data and predicting oil consumption rates.Engine data are cleansed using density-based clustering algorithms,including density-based spatial clustering of applications with noise(DBSCAN),to obtain stable oil quantity dat…查看全部>>
