| 摘 要： | 本文提出一种根据脂的实测表观粘度拟合成四参数流变模型的方法。运用加权残量法导出了纯滚动脂润滑一维流动的当量雷诺方程,并采用Chris-tensen的简化全数值解,通过多次迭代使表征非牛顿效应的参数收敛,以逼近不同工况下的实际流动,进而得出了脂润滑线接触中心膜厚公式。由光干涉实验证明本文理论计算结果与实际非常接近。

| Abstract: | An algorithm by fitting apparent viscosity test data to obtain a four-rheological-parameter constituent equation of grease is advanced. Makinguse of weighted residue method, derived is the equivalent reynolds equation. Numerical complete solution is acquired adopting Christensen's rigid stamp model. Iteration scheme is employed until finally the non-Newtonian effect parameter is satisfactorily converged. The agreement between theoretical and experimental results is good. |
