| 摘 要： | 利用一种快速求解弹流方程的完全数值方法，求解了包含挤压项的非稳态部分弹流的Ｐａｔｉｒａｎｄｃｈｅｎｇ的平均流动模型以及吴承伟和郑林庆的接触因子模型，深入地研究挤压条件下油膜形状、压力分布动态变化特征，对于上述两种模型数值解的差异也在较宽的参数范围内给予了讨论，为更加直观、简单的部分弹流问题的接触因子模型的工程应用提供了理论依据。

| Abstract: | By adopting a kind of full numerical algorithm of fast solving EHL problem.this paper solved un-steady partial Reynolds equation which contains squeeze term with the Patir and Cheng' s averge flow model and the Wu Cheng Wei and Zheng Lin Qing' s contact factor medel.The differences between the numerical solutions of these two models are compared, and the dynamic change character of a micro-peak contact is also studied.The result provides a theoretic basis for engineering application of the par-tial elasto-hydredynamic problem with the contact factor model which is more intuitive and simpler. |

| Keywords: | unsteady partial elasto-hydrodynamic lubrication contact factor half band width of iterative matrix |
