| Abstract: | A numerical solution for the problem of elastohydrodynamic lubrication(EHL)of line contact grease under high loads is presented by using a multi-grid method.Thecalculation results reveal that the pressure distribution under the high loads is near toHertzian.The yield stress has less effect on the film thickness. |
