Abstract:

The hydroforming process offers several advantages as compared with conventional manufacturing via stamping and welding, such as part consolidation, weight reduction, improved structural strength and stiffness, lower tooling costs, fewer secondary operations, tight dimensional tolerances, low springback, and reduced scrap. In this study, the estimation of the process parameters for hydroformed Y-shapes (i.e. pressure levels, axial feed and counter punch force) is discussed. Application of the simulation methods to the development of the hydroforming parts is illustrated. Numerical simulations of the tubular Y-shape element were conducted using the commercial ABAQUS explicit finite element code.
