In this paper, the bending process of thin-walled tubes by rotary draw method is initially simulated in ABAQUS software.Then the necessary experiments are carried out, and the simulation results associated to the quality of the product in terms of changes in the wall thickness and ovality of the cross section as well as the required moment for tube bending are compared with the empirical findings. The comparison demonstrates the high accuracy of the simulation results. The required moment is also calculated by the stress analysis method, and an integrated discussion is made over the errors of simulation, experiment and analytical stress analysis.
