Numerical Analysis for the Bending Process of Profile with Stiffener

Abstract:

Aluminum alloy profile has been widely used in manufacturing industry for weight reduction. In the bending process of profile, the cross-section distortion is a common defect and also springback always happens in unloading process. In the paper, the bending process of a hollow profile with stiffener was simulated to optimize the forming parameters. Different bending radiuses and inner pressure were chosen in FEM analysis and the suitable radius and calculation equation of pressure for the given profile were obtained. The springback at different bending radiuses were studied to provide the principle of shape compensation.
