Abstract

The study focused on numerical and experimental investigations of steel head restraint produced via the technology of cold rotary swaging. The analyses were carried out via finite element modelling and experimental swaging; the whole study was supplemented with 3D scanning. The experimentally swaged work-piece was scanned and eventually compared with the final product from the simulation. The results showed a good correlation of the swaged and predicted shape of the final head restraint. The numerical simulation focused especially on the distribution of equivalent imposed strain and a possible increase in temperature due to the development of deformation heat. The experimental part was supplemented with examinations of mechanical properties, and microstructure observations.
