摘要
本文应用A.C.Eringen的微极流体理论,对含有固体微粒添加剂的润滑流体进行线接触弹流润滑理论分析。对于不可压缩的微极流体,采用Newton-Raphson法求得等温弹流润滑的完全数值解,从而获得不同工况下弹流润滑的压力分布和油膜形状。计算结果表明,微极流体较之牛顿流体,其压力分布无明显改变,而油膜厚度则显著增加。
The micropolar fluid theory by A. C. Eringen is used to analyze the elastodrodynamic lubrication for line contact with the lubricant containing solid-particle additive. A full numerical solution of isothermal EHL for the incompressible micropolar fluid is obtained by means of the Newton-Raphson method. The pressure distribution and film shape of EHL under various working conditions are presented. The results show that the pressure distribution remain mearly unchanged and the film thickness increases obviously in comparison with the Newtonian fluid.
