摘要

黏度是润滑油的重要性质，黏温特性对开展润滑油在线监测具有重要意义，选用了6种车辆动力和传动系统常用润滑油作为研究对象进行润滑油的黏温特性研究。首先，通过试验方法测定了选用油品的黏温数据，并分析了润滑油黏度随温度变化的特点。然后，利用回归分析方法，评估了现有黏温方程对选用油品黏温数据的拟合精度和预测误差。在此基础上，建立了一个新的黏温方程。试验结果表明，与现有黏温方程相比，改进的黏温方程在描述选用油品10~120 ℃温度区间的黏温特性时更加准确，同时也为润滑油在线监测提供了新的依据。

Abstract

Viscosity is an important property of lubricating oil, and its viscosity-temperature characteristic is of great significance to carry out online monitoring of lubricating oil. To study the viscosity-temperature characteristics of lubricating oil, 6 types of lubricating oil commonly used in vehicle power and transmission system were selected as research objects. Firstly, the viscosity-temperature data of selected oil were measured by the experimental method, and the characteristics of lubricating oil viscosity changing with temperature were analyzed. Then the regression analysis method was used to evaluate the fitting accuracy and prediction error of existing viscosity-temperature equation for selected oil viscosity-temperature data. A new viscosity-temperature equation was finally established. The experimental results show that the improved viscosity-temperature equation is more accurate in describing the viscosity-temperature characteristics of selected oil at the temperature range of 10 ℃ to 120 ℃ compared to the existing viscosity-temperature equation, thus providing a new basis for online monitoring of lubricating oil.
