Abstract：

The current design of hydroforming loading path mostly belongs to trial and error method without systematic guidance in path debugging and quantitative feedback. So a design method of hydroforming loading path based on the uniform capacity change was proposed. Taking the linear uniform change of internal volume with axial feeding as target, the hydroforming process was divided into several substeps. By adjusting the internal pressure of tube in each substep, the internal volume of each substep was adjusted along with the uniform capacity change line, and the hydroforming tube part was obtained. For the preformed tube of a large automobile axlehousing, the loading path of uniform capacity change was obtained by numerical simulation, and the reasonable forming range based on uniform capacity capacity change line was given. Furthermore, the preforming productivity test was carried out, and the samples with clear profile, thinning rate of wall thickness met design requirements were obtained. The results show that the designed method based on uniform capacity change is suitable for guiding practical production, and the sample has high yield and good formability.
