摘要：Questions of experimental study regarding the stress-strained state in the radial rotary method of producing the steel rims of wheels are examined. The physical simulation of the process of profiling the rims is performed on the installation, designed especially for these purposes. The models of the narrow-profile and wide-profile rims of wheels were tested. The grids method was applied for conducting the experiments. The obtained information was processed by the methods of mathematical statistics and probability theory. The results of experimental data made it possible to arrive at a conclusion about the most dangerous sections of the profiles of the rims of wheels, which, in the process of deformation, obtain compressive radial deformations, which confirms the studies conducted previously. The largest deformations occur in the places of radius couplings of the profile, deformations increase from one transition to the next and their total magnitude can exceed the permitted by 20 % of the initial thickness of the workpiece. No essential difference between the two schemes of profiling the rims of wheels was revealed.
