MULTIPOINT BLANK
HOLDER FORCE CONTROL IN HYDROFORMING OF FUEL TANK*
Abstract:
The study of multipoint blank holder force (BHF) control is carried out for hydroforming a complicated shape motorcycle fuel tank. By finite element method (FEM) simulation, the configura-tion of multipoint blank holder cylinders and the setting of local BHF are optimized, and the influ-ences of the multipoint BHF on the hydromechanical deep drawing and conventional hydroforming processes are studied. The desired fluid pressure and whole BHF are predicted for hydromechanical deep drawing process. Finally, simulation results are testified by forming experiment, and they are in agreement very well.
