Abstract: 3D non-linear FEA technique is used to simulate the whole process of empty-sinking steel tube dynamically based on LS-DYNA module of ANSYS. Distributions of relevant field variables are obtained. So the mechanisms of the problem which often cause transverse fissure and longitudinal fission etc in production are analyzed. Based on the rules of drawing force, drawing process is divided into three stages: start, flow, stable. The relationships of processing parameters and drawing force are achieved. Thus Foundation is laid for optimal design of die structure and technological design of Empty-sinking steel tube.
Keywords: ANSYS/LS-DYNA; Empty-sinking steel tube; Finite element; Drawing force
