Research on the Springback Regularity of Curved Edge Bending

Abstract:

Rubber bladder hydroforming is one of the most important technology in the aircraft manufacturing industry.The springback seriously restricted the one-step forming.This paper is a research on the springback angle of straight edge bending and curved edge bending by using FEM software PAM-STAMP2G .Comparing the angles between the straight edge bending and the curved edge bending to get the springback regularity along the circumference.The springback angle of the curved edge bending changes along the circumference closing to a parabola and the springback angle of the edge is approaching to that of straight edge bending.
