Firstly ,this paper studied the critical values of the rectangular box’s wrinkling and fracture when using the traditional binder .Secondly ,the concept of binder with hydrostatic support and flexible segmented was put forward ,and the software of CFX+ANSYS was used to conduct the fluid structure coupling analysis . Thirdiy ,the orthogonal tests were carried out through DYNAFORM to obtain the minimum thickness data ,and the optimal combination was achieved between F1 , F2 and F3 .The symbols of F1 , F2 and F3 represent the forces of the long flange ,circular corner and short flange ,respectively .Lastly ,the stam-ping experiments were carried out on the stamping experiment system and the results were compared with the those gained by the software of DYNAFORM .
