Finite Element Analysis on the Roll Milling Process of Twisted Oblate Tube
The roll milling process for manufacturing a twisted oblate tube was presented and applied in the forming of twisted oblate copper tube successfully. A finite element simulation of the roll milling process for forming a twisted oblate 1010 steel tube was implemented on the basis of the elastic-plastic explicit dynamic finite element method under the ANSYS/LS-DYNA environment. The simulation accuracy was verified by comparing the forming force from simulation with the experimental results. The forming effect, change curve of forming force, tube stress distribution and influences of forming parameters on forming force were investigated. The simulation results can be guidance to the manufacturing process improvement and manufacturing equipment design of the twisted oblate steel tube.
