ROLLING OPERATION

AIM

TO Simulate the rolling operation on a copper workpiece

PROCEDURE

• Open ansys workbench .
• Update the material module as COPPER ALLOY (Nl).
• Geomtery - import-ROLLING OPERATION
• In the space claim module edit the model with 60mm height and extrude lenght of 8mm on each side.
• Model-edit
• Rename the model.
• Assign copper only to the WR.
• Then create a contact between the wheels and WR.
• The normal stiffness factor = 0.1.
• Stiffness should be assigned to each iteration.
• Then Add offset ramped effects.
• Then create joints between The models.
• Then mesh with element size of 4mm and sizing is done only to WR.
• Then upadte the analysis settings.

• Then displacement is given negative Y direction to emulate the simulation.
• Then request all the ouputs.

STRESS

MAX= 2783.9 MPA.

MIN = 0.0006 MPA

PLASTIC STRAIN

MAX=1.6651MM/MM

MIN = 0.00046MM/MM

DIRECTIONAL DEFORMATION

ABOUT Y AXIX

DIRECTIONAL DEFORMATION

ABOUT Z AXIX

CONCLUSION

• The maximum equivalant stress for the whole setup is 2783.9MPA
• The maximum equivalant strain is 1.6551mm/mm
• Directional deformation about z axix is 6.323 , which indicates how much it has been deformed.
