Abstract：

The traditional design methods of blank holding force were summarized.The availability of the traditional empirical formulae of blank holding foree(BHF)was analyzed while using high strength steel instead of ordinary deep drawing grade The limitation of traditional empirical formulae to be applied to deep drawing of high strength steel pan- els was figured out.Then the sensitivity of the formability and accuracy to BHF for different kinds of steels were com- pared and the reasons were further analyzed by strain hardening and forming limit curves.The results above provide a foundation for the BHF design for high strength steel sheet.
