in this paper,the action and importance of displacement boundary condition during theblank holding stage were analyzed. In the finite element simulation, the method of automatic judgingcontact and loading displacement was presented to determinate the displacement boundary condition. Us-ing this method, the author caculated the sheet metal deforination during the blank holding stage and got the result which agreed well with the expenment.
