中文摘要:
      为计算在用油剩余有效寿命,从而科学确定换油周期,以酸值为润滑油寿命表征指标,基于氧化动力学基本原理,通过模拟实验,分析温度、水分等工况条件对酸值的影响。通过温度与反应速率的线性回归计算活化能,并建立润滑油在特定温度下的寿命方程。结果表明:工作温度的升高会显著缩短润滑油的剩余有效寿命,水分通过改变反应活化能影响润滑油的使用寿命;基于氧化动力学Arrhenius方程建立的润滑油剩余寿命模型,通过模拟实验分析特定性能指标的变化率,可快速获得润滑油的预测寿命。
英文摘要:
      To calculate the remaining useful life(RUL) of lubricating oils and determine the change oil cycle scientifically,acid number(AN) was taken as characterization index,the influence of operating condition,such as temperature and moisture on AN was analyzed through simulation experiments based on the basic principles of oxidation kinetics.The activation energy was calculated by the linear regression of temperature and reaction rate,and the lifetime equation of the lubricating oisl at a certain temperature was established.The results indicate that the increase of working temperature can significantly shorten the RUL of lubricating oils,and the moisture can affect the service life of lubricating oils by changing the activation energy of the reaction.Based on the residual life model of the lubricating oils established by the Arrhenius equation of oxidation kinetics,the RUL of the lubricating oils can be obtained quickly by analysis of specific performance indicators through simulation experiments.
