An Analytical Comparison of Single and Bi- ayered Tube Hydroforming Systems Using Finite Element Method

摘要

Tube hydroforming is a type of unconventional metal forming process in which high fluid pressure and axial feed are used to deform a tube blank in the desired shape. Single and bi-layered tubular components can be produced by this method. In this paper, single and bi-layered tube hydroforming processes were numerically simulated using finite element method. It was found that the developed branch height resulted from the models was in good agreement with the experimental results. Both types of modeling have been kept with the same thickness, tube material, and process parameters to compare between the obtained hydroformed products (Branch height, Thickness reduction, and wrinkle height). Results were discussed.
