测量了HKD型航空润滑油的拖动力,确定了该油的本构方程,给出了本构方程中各种流变参数的计算方法并拟合出了计算公式,给出了拖动力的计算方法。结果表明:该油在试验条件下表现为粘弹性;拖动力的理论预测值与试验测量值之间误差较小,曲线形状一致,本构方程正确合理;流变参数的拟合公式精度较高。
The drag force of HKD type aviation lubricating oil was measured, the constitutive equation of the oil was determined, the calculation method of various rheological parameters in the constitutive equation was given, the calculation formula was fitted, and the dragging force The calculation method. The results show that the oil shows viscoelasticity under the experimental conditions; the error between the theoretical predictive value of the drag force and the experimental measurement value is small, the shape of the curve is consistent, the constitutive equation is correct and reasonable; the accuracy of the fitting formula of the rheological parameters is better high.
