This paper presents a control model of the hydroforming and the dual hydroforming process of a tube. The theoretical part includes calculations to measure the change in tube thickness through the developed process. The hydroforming and the dual hydroforming processes are simulated in the SOLIDSIMULATION software and the static and the dynamic simulations are modeled. The obtained results for the T-shape and the X-shape dies are compared and investigated. Moreover, the developed software in MATLAB calculates the process parameters. The inputs of the developed software are the maximum internal pressure and the axial feed that could be adjusted with linear and non-linear functions. Furthermore, the material of the tube, as well as the tube’s parameters, such as length, thickness, and radius, must to be given to the software. However, the properties of the tube could automatically support the CAD model. The software-generated results are the applied stress, displacement, and the energy through the process. This paper deals with the control strategy model developed in thesoftware packages. The obtained results are then subsequently compared with those of several experiments.
