Tube hydroforming technology has shown the attention of the automotive industry due to its advantages over conventional stamping and welding methods. In this study, the tube hydroforming process including tube bending, preforming and hydroforming process for an automobile subframe is analyzed and designed by the simulation software AutoForm of a finite element method (FEM) program. A parametric study is carried out to obtain the effect of the forming parameters such as initial tube size and loading path on the forming results. The simulation results are also compared with experiment results. The research indicates that the multiple forming operation of the tube hydroforming process can be simulated accurately by using the implicit code AutoForm, and the formability of tube hydroforming can be improved by designing suitable forming parameters.
