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。 In this paper, A.C.Eringen’s micropolar fluid theory is applied to the theoretical analysis of the contact lubrication of the lubrication fluid containing solid particulate additives. For the incompressible micropolar fluid, Newton-Raphson method is used to obtain the complete numerical solution of isothermal EHL, and then the pressure distribution and oil film shape of the EHL under different conditions are obtained. The calculated results show that compared with Newtonian fluid, the pressure distribution of the micropolar fluid does not change significantly, while the thickness of the oil film increases significantly.
