Week 4- Rolling operation

Aim: To simulate the rolling operation on a workpiece made of copper.

Procedure:

• Initially add the 'Static structural' to the interface.
• Then add the 'copper' material to the engineering data.
• Next, import the CAD model to the geometry and open the SpaceClaim to edit the model.

• Then load the mechanical model to set up the solution.
• Then add the material 'copper' to the workpiece.
• Then define the 'Frictional contacts' with the coefficient of friction as 0.2 as follows,

• Then, apply the 'Body Ground' cylindrical joints to the rollers

• Next, mesh the model with an element size of 2 mm.

• Next, set up the analysis settings for 14 steps to run the simulation as follows,

• Then, add the displacement to the workpiece such that it should be rolling in between two rollers in a negative Y direction.

• Then, define the joint load to both the rollers as follows,

• Then add the Equivalent stress and Total deformation to the solution and run the simulation.

Results:

• Equivalent stress:

• Maximum stress developed on the workpiece is 2806.3 MPa

• Total deformation

• The maximum deformation is 84.773 mm.
• Directional deformation:

• Plastic Deformation of a workpiece:

Conclusion:

• Hence the simulation of copper rolling is done successfully.
