Week 4- Rolling operation

OBJECTIVE:

• To set up the model for rolling operation and find the necessary solution

STEPS:

Import materials:-

• Import the required materials for the simulation
• Go to Engineering Data>Engineering Data sources>General Non linear materials>Copper alloy NL

Import Gepmetry:-

• Import the model from saved loacation
• Open the space claim and edit the workpiece
• Increase the length by 60mm and Reduce the thickness by 8mm
• Now update the model and enter to Mechanical workbench

Define contact:-

• Flip the default contact
• Define the connection between the wheel 1-workpiece and wheel2-workpiece
  

Define Joints:-

• Define a Revolute joints for both the wheels
• Make sure the direction of rotation is proper

Mesh:-

• Body sizing the workpiece with 4mm element size
• Global mesh size will be 5mm
  

Analysis Settings:-

• Create a Analysis setting for 14 steps
  

Define load:-

• Define a displacement load for workpiece
  
• Define joint load for Wheel 1, in clockwise rotation
  
  
  
• Define joint load or wheel 1, in counter clockwise rotation
  

RESULTS:-

1. Equivalent stress =2339.2 Mpa
   
   
   
2. Equivalent plastic strain=1.3487 mm/mm
   
   
   
3. Directional deformation in Z direction=5.5454mm
   
   
   
4. Directional deformation of workpiece in Y direction=90mm
   

CONCLUSION:

• We can see the above results, the maximum stress is generated in the workpiece
• The maximum deformation in Z axis is 5.454mm
• We can conclude the total displacement of workpiece is 90mm, by seeing the results of maximum directional deformation in Y axis is also 90mm
• Hence we can tell the workpiece is displaced by 90mm
