Simulation of the Reconfigurable Tubes Hydroforming Technology

Résumé

Tube hydroforming (THF) has become a viable method for manufacturing complex automobile parts and an indispensable manufacturing technique in recent years. Coordination of the internal pressurization and axial feeding curves is critical in the tube hydroforming process to generate successful parts without fracture or wrinkling failure. In the paper are presented some comparative results about the tube hydroforming process of a symmetrical part, considering as the main parameter the presence or the absence of the axial feeding of the punches.
