摘　　要：在弹流润滑研究中,通常假设粘度仅受压力和温度的影响,而不受边界效应的影响。当油膜较厚时,边界效应对弹流解的影响不大,但在油膜很薄的情况下,考虑了边界效应得到的膜厚要远远大于未考虑边界效应得到的膜厚,此时边界效应不应忽略。作者用粘度修正的方法将边界效应考虑进去,并得到了考虑边界效应的等温弹流解。Elastohydrodynamic studies have been mostly in the case when the viscosity of the lubricant restricted by pressures and temperatures only,but isn’t influenced by the solid surfaces.When the film is thick,the effect of boundaries is not important,but when the film is very thin,the film thicknesses considering the effect of boundaries are much larger than those without considering the effect of boundaries,then the influence of solid boundaries should not be ignored.The effect of boundaries have been taken into account with the method of modifying the viscosity of the lubricant in this paper,and numerical isothermal results have been obtained.
