Owing to its versatility and the ability to provide the final products with advantageous characteristics, rotary swaging is widely used in automotive industry for production of various components. The focus of this study was to perform numerical prediction of rotary swaging of a steering tube. The predicted results were subsequently evaluated with data gained from experimental swaging. The analyses carried out on the experimentally swaged model included measurements of microhardness, as well as scanning electron microscopy observations. To evaluate reliability of the simulation, the simulated swaged component was compared with a 3D-scanned real product. As shown by the results, the parameters of the dies and processing conditions defined in the simulation corresponded very well with the real process and thus the designed numerical model can be considered as an accurate one. The swaged product featured a very smooth surface and small equiaxed grains, 80 % of which were smaller than 1 µm, with no prevalent grains orientation.Keywords: rotary swaging; automotive; numerical simulation; structure analysis; mechanical properties
