Abstract：

Using simulation software ABAQUS, the tube bending process was simulated. The effects of relative bending radius R/D, friction condition and bending angle on the change of wall thickness were researched. The results indicate that with the increase of relative bending radius, the thinning-rate of wall thickness in the outer side of tube and the thickening-rate of wall thickness in the inner side of tube trend to decrease. With the increase of the friction coefficient, the thinning-rate of wall thickness in the outer side of tube and the thickening-rate of wall thickness in the inner side of tube will increase rapidly. The bending angle is larger, the thinning-rate and the thickening-rate of wall thickness are greater. By experiments, the result is basically consistent between numerical simulation and experiment.
