Comparative Analysis of Onestep and Multistep Forming in Automotive I/P Beam Hydroforming Process

Abstract:

After a brief introduction of state of art of hydraulic forming technology in China and abroad, the simulation experiment and finite element model of the directly forming and step-by-step forming are designed. According to the different characteristics of forming and spring back, the simulation analysis are performed through dynamic display algorithm and statistic implicit algorithm, and analyze the influence on tube thickness, spring back amount and the final residual stress of two different manufacturing processes which is compared with the experimental result. The comparison result can provide some theoretical reference for dashboard beam hydraulic forming process design, process parameter setting and mold design.
