摘　　要：利用Herrebrugh给出的无量纲最小油膜厚度和弹性参数的数值计算结果,得出了在弹性-等粘润滑状态下,两者之间的关系式。在弹性-变粘润滑状态下,对Dowson油膜厚度公式进行了修正,给出了新的油膜厚度公式。计算结果表明,提出的油膜厚度计算公式计算结果更符合实测值。A new related equation of the least oil film thickness of non-dimensional and elastic parameter at the state of isoviscous-elastic lubrication was presented based on the numerical value results figured out by Herrebrugh. On the condition of piezoviscous-elastic lubrication, the equation of Dowson＇ s oil film thickness was revised, and a new oil film thickness formula was given out. It is showed that the calculation result of the presented oil film thickness formulae accords with the test data.
