| Abstract: | A Study of the elastohydrodynamic lubrication of journal bearings has been given in this paper.The influence function,which is used to calculate elastic deformation,is obtained by the finite element software MARC.The hydrodynamic lubrication performance that doesn't take elastic deformation into consideration and the elastohydrodynamic lubrication performance of journal bearings have been compared. The results tally with the existing literature,which indicate that using influence function method in the elastohydrodynamic lubrication analysis of journal bearing can have favorable precision. |
