This article puts forward One-step forming simulation method to solve blank outline problems in the process of sheet metal forming. The blank outline curve is got from the simulated analysis of Groupware of Fender by one-step simulation in Dynaform 3D software for sheet forming, considering the final shape of the workpiece. It simulates three programs via three different shapes of blanks. And it compares and analyze the FLD diagram and forming results ,and then it gets the optimized blank shape. This way guides the mould design, and save the time of repairing moulds on the basis of producing qualified products. It overcomes the puzzle how to choose the blanks’ size and shape.

The One

A simplified one-step inverse analysis of sheet metal forming is a suitable tool to simulate the bending forming since the deformation path of bending forming is an approximately proportion one. A fast spring-back simulation method based on one-step analysis is proposed. First, the one-step inverse analysis is applied to obtain the stress distribution at the final stage of bending. Then, the unloading to get a spring back is simulated by LS-DYNA implicit solver. These processes are applied to the unconstrained cylindrical bending and the truck member rail. The spring-back and member rail widths at the several key sections are compared with experimental ones. It is well demonstrated that the proposed method is an effective way to predict the spring-back by unloading after bending process.
