Abstract

In order to study the effects of geometrical parameters on wrinkling of 0Cr21Ni6Mn9N stainless steel tube in numerical control (NC) bending process, a three dimensional elastic plastic finite element model of the 0Cr21Ni6Mn9N stainless steel tube in NC bending was established based on ABAQUS/Explicit code, and its reliability was validated by experiment. Then, simulation and analysis of the effect rules of the bending angle, relative bending radius and relative tube diameter on wrinkling wave ratio were carried out. The results show that the wrinkling wave ratio increases with the increasing of the bending angle, and the amplitude of the increase slows down. The wrinkling wave ratio decreases with the increasing of the relative bending radius or decreasing of the relative tube diameter. The research results provide beneficial knowledge on bending behaviors of 0Cr21Ni6Mn9N stainless steel tube under different geometrical parameters and help efficient design and optimization of the forming parameters.
