Analysis of the tube hydroforming by numerical simulation and Response Surface Methodology

In this research mathematical model was developed utilizing the 3D finite element method and response surface methodology to describe the tube hydroforming production process. This paper is an example of the relatively simple analysis of the influence of the technological parameters on hydroformed T-shaped tube protrusion height, diameter, and thickness utilizing statistical analysis and 3D finite element analysis in the QForm UK 10.2 commercial software. Therefore, this paper could be beneficial for both researchers and engineers interested in tube hydroforming design guidelines and simple optimization methods. The influence of the hydroforming die radius filler, axial tool displacement, and counter punch force on the T tube protrusion height, diameter, and thickness was described and optimized.
