Verification of results of swaging process simulation

The paper presents some basic assumptions of the model which allows and ana lysis of the thermomechanical state in the deformation zone with the use of finite elements method for axial symmetry. The model has been elaborated f or four - anvil swaging machine for primary processing. The modelling proce ss takes into account the history of deformation for subsequent forming sta ges. The suggested assumptions and calculation conditions of the model have been verified experimentally. The obtained calculation results have been compar ed with the results of forging tests in industrial conditions. As far as th e local strain is concerned the results of calculations have been compared with the results of measurements of strains obtained by the combined bars m ethod Temperature distributions in the strip section have also been verifie d and compared with the results of pyrometric measurements of temperature a t the bar surface. The forging forces have also been experimentally verifie d. The results of measurement proved to be consistent with the simulation resu lts what confirms correctness of the assumption in the model. Calculations showed that simulation of the forging process in a swaging machine creates a rational basis for proper forging technology design, when safety of the p rocess, as well as requirement for bar forging with an assumed strain and s tress distribution at the bar section, are taken into consideration.
