摘要

Reynolds equation was deduced based on Evans-Johnson model, and Numerical solution for isothermal line contact EHL was conducted successfully using multigrid method. Slow movement of lubricant through the contact area leads to oil film thickness decrease seriously. Newtonian Theological model is no longer applicable When slide-roll ratio is larger than 0.6. . Second pressure-peak is decreasing with increasing slide-roll ratio. Under heavy load and large slideroll ratio conditions lubricants in different regions showed different Theological behavior.
