In order to improve the forming precision of the stretch bending process for T sectionaluminum extrusions and meet the fine forming requirement of the aerostat blank parts, theelongation controlled stretch bending process finite element model is proposed, which is based onthe basic principle of the stretch bending forming with respect to A-7B CNC Section Stretch WrapForming Machine by analyzing various factors that influence the qualities of stretch bending parts,and the numerical simulation of the stretch bending process and spring back for T section aluminumextrusions is carried out. The results of simulation show that the pre-stretching elongation has amajor effect on stretch bending parts and finite post-stretching elongation helps to improve theforming qualities of the parts. Comparing with the experimental results, the spring back of the finiteelement simulation shows good agreement with that of the experimental results
