摘要

In order to study the free bending forming process of tube, the basic principle of free bending is analyzed. The mechanical properties of the material are obtained by tensile test. The thickness reduction rate and ellipse ratio are selected as the evaluation indexes. The free bending finite element model of the tube is established by ABAQUS finite element software, and the three-dimensional free bending simulation of the tube is carried out. The simulation results show that the bending tube has good forming quality. In the subsequent work, the free bending forming experiment of the tube is carried out to verify the effectiveness of the simulation process parameters.
