| Abstract: | The FEM model for L-shaped tube has been built by use of 3D finite element analysis(FEA) software Deform-3D.The motion simulation of the bending process has been carried on.The influence of tube equivalent stress,velocity,and the material damage distribution on the tube quality has been simulated and analyzed,as well as the influence of die clearance and mandrel.The forming faults have been analyzed.The bending tube which meets the requirement after optimization has been obtained. |
