Analysis of Thermoelastohydrodynamic Lubrication of Sliding Surfaces with Zero Entrainment Velocity

  • 摘要: 提出了接触处两表面等速反向运动的圆柱间在一定条件下赤存在足够厚的稳态热弹流膜,此时固体表面呈现中凹状、且凹陷深度随勒荷的增加而增大,随表面速度的增加而减小。

     

    Abstract: The entrainment velocity is generally considered essential in the traditional steady state elastohydrodynamic lubrication theories. However, a steady state thermal elastohydrodynamic lubrication film of enough thickness could be formed between the contact surfaces of two cylinders moving at a velocity of the same magnitude but in opposite directions (referring to an entrainment velocity of zero). In such a case the contact surfaces take a shape of concave in the middle, and the concavity increases with increasing load but decreases with increasing surface velocity.
