A hydrodynamic lubrication model for the deep-drawing process |
|
| Authors: | S M Mahdavian D He |
| Abstract: | A steady hydrodynamic lubrication model that includes the pressure viscosity factor has been developed for the deep-drawing process. Equations for lubricant film thickness, radial and drawing stresses are presented. Analysis reveals that the pressure viscosity factor has a significant influence on estimating lubricant film thickness and radial and drawing stresses. |
