Numerical Simulation of Hydro-Forming Process of Shaped Tube

Abstract:

in the forming process of section tube using hydro forming, distributed regulation of the strain, loading rate and destabilization have a large influence to forming. The forming process is simulated by means of FEM in this paper. Simulation results shows that strain are maximal at the convexity and concave of die. And with pressure increasing, the phenomenon of destabilization would occur on some side of its convexity randomly, the forming process of section tub can be divided into two obvious stages. Besides, critical pressure of two stages is pointed out. The simulation results are compared with the experiment results, and the correctness of the simulation is verified.
