Abstract：

Deep drawing experiment of cylindrical part was done with the blank holder force(BHF) determined by a BHF model based on energy method.The forming effect was good.The model was corrected by collecting true strains from component flange and using least square method.The corrected model is more favorable for the forming and facilitates the cylindrical part's formation,whose deep drawing coefficient is slightly less than the limit deep drawing coefficient.The model is applicable for box-like part drawing and the result is also good.
