Numerical Simulation of Discrete Die Bending of Rectangular Tube

Abstract:

The concept of discrete die bending of rectangular tube is proposed, and the FE model is set up. The phenomenon of section distortion of rectangular tube generated by discrete die bending is analyzed. The feasibility of discrete die used for bending of rectangular tube is proved by comparing the section distorted rate generated by both discrete die and integral die. A lots of numerical simulation of the influence factors of section distortion are analyzed, the results show that larger the bending radius is or the thicker the rectangular tube is or the larger the yield strength of rectangular tube is, the smaller the section distorted rate will be. Then the dimple generated by discrete die is described, and the influence factors are studied, the results shows that the smaller the bending radius is or the thinner the rectangular tube is or the smaller the yield strength of rectangular tube is, the stronger the dimples on the rectangular tube will be.
