摘    要:应用微极流体理论,考虑流体的可压缩性,建立线接触微极流体动力润滑的基本方程,进行固液两相流体稳态流动弹流润滑数值分析,获得了润滑油膜压力、形状以及摩擦力分布,分析了微极参数对润滑性能的影响,并与不可压缩流体结果进行比较。结果表明,固液两相润滑流体较单相牛顿流体,在增加膜厚、提高承载力方面有显著的作用,而接触表面的摩擦因数有所降低,流体的可压缩性降低了油膜压力与油膜厚度。

关 键 词:固液两相润滑剂  弹流润滑  微极流体  微极参数

Abstract:The basic line contact elasto-hydrodynamic lubrication(EHL) equations for micropolar fluids were developed on the basis of the theory of micropolar fluids.The compressibility of lubricants and micropolar parameters were introduced.A full numerical analysis of EHL for two phase liquid-solid lubricants was conducted.The variation of pressure distribution and film profile along the contact line of rollers,and effects of the micropolar parameters on lubrication behaviors were obtained.Compared with the Newtonian fluids,the liquid-solid lubricants predicts obvious enhancement of film thickness and ability of load,slightly reducing of coefficient of friction.The compressibility of lubricant reduces the film pressure and thickness.
Keywords:two phase liquid-solid lubricants  elasto-hydrodynamic lubrication  micropolar fluids  micropolar parameters
