| Abstract: | The finite element simulation on a new hydro-mechanical deep drawing process was studied. A hydro-mechanical deep drawing die was developed in which hydraulic pressure will form the radial thrust, frictional preservation and fluid lubrication effect. The finite element model for the new tool was established. The radial thrust force was modeled by means of nodal force and the fluid pressure in die cavity was modeled by element force. Simulation calculations were performed for 08A1 drawing steel plates based on the finite element model and actual experiment parameters. The results of simulation agree well with experiment ones. The validity of the model was verified. |
