Abstract

This study investigates the influence of internal pressure and axial feeding loading paths on the quality of tubes in the hydroforming process. Numerical simulations were conducted to examine the effect of loading paths on final part characteristics, including thickness distribution and shape conformance. Finite element analyses were performed on small bulge-shaped copper tubes with a bulge width of 50 mm, wall thickness of 2 mm, and an outer diameter of 60 mm. A two-dimensional model was developed from a cylindrical tube, and simulations were conducted using ANSYS 11. Results indicate that the choice of loading path significantly affects the thickness distribution along the tube and determines the ability to achieve the target shape of the final product. The study provides practical guidelines for optimizing internal pressure and axial feeding programs in tube hydroforming operations.
