Abstract
This paper presents the simulation results on prebending and hydroforming p rocesses that are used to form an automotive part, a tie bar. Two prebendin g simulations, by a rotary draw bending machine and a bend die, are carried out to obtain the shape change of the cross-section and the thinning of th e cube and the results are compared with each other. In prebending simulati on with a rotary draw bending machine, to avoid wrinkling in compressive ar ea of the tube, a wiper die is included. A parametric study is carried out to obtain the effect of the forming parameters such as bend radius and tube thickness. The hydroforming process is simulated considering the results o f the prebending simulation. (C) 2001 Elsevier Science B.V. All rights rese rved.
