Numerical Simulation of Hydro-Forming Cylindrical Cup with a Hemispherical Bottom
In order to improve the hydro-forming accuracy, the process parameter’s effect on the technology was studied by using finite element method. The numerical simulation model of the forming process was established. The deformation and thinning were studied. The FLD was used to determine the safe limit of the sheet metal operation. FLD showed that the cylindrical hydro-drawing process could be successfully done in one stroke.
