Numerical simulation of thin wall Ti-tube heating bending process with large diameter

Ping Zhang

Abstract

Finite element software ANSYS was used to simulate the thin wall Ti-tube heating bending process with large diameter.The finite element model of tube heating process and the finite element model of tube bending process were established respectively with ANSYS parametric design language APDL.The models could fit different tube diameter,bending radius and mould dimension.The results show that the heating temperature significantly influence the quality of tube bending process,and the quality of tube bending process is well when the heating temperature at 650 ℃ to 700 ℃.
