Week 5 Challenge : Surface wrap on Automotive Assembly

Surface wrap on Automotive Assembly

Aim:

To surface wrap on given automotive assembly.

Objective:

Surface wrapping for the following component

1. Engine
2. Gearbox
3. Transmission

Procedure:

1. Topo Clean up:

• Open the file from the location where we have saved it on our Computer by using the “Ctrl+O” Command.
• Go to the Tool in the ansa
• Select the check
• Left click on geometry check
• Select the following check-in geometry check

1. Single cons
2. Cracks,
3. Overlap faces
4. Needle faces
5. Trible cons
6. Collapsed cons
7. Unchecked faces

• Delete the unwanted surface.
• Remove single cons by creating a new surface.
• Delete the overlapped surface by Delete the Surface which is overlapped.
• Remove the extended surface by deleting the extended entities and creating a new surface.
• Eliminate void surface by creating the new surface in ansa.
• Check the single Cons by using wireframe mode in ansa by using the combination of the Ctrl+Shift keys.
• Close the open hole by creating a new surface.
• Delete the tube connection.

2. Creating PID

• Go to the PID manager
• Create new PID
• Assign the color for each surface according to the PID we created.
• Apply the PID to the Surface.
• Edit the PID according to the given name.
• Compress the unwanted PID.

3.2D mesh:

• Go to the mesh deck and give the perimeter value, and macro value as a target length.
• Assign the mesh parameter value
• Go to the quality Criteria and give the minimum and maximum values.
• Go to the mesh deck,
• Pick the spot mesh. Then select the component by using the select command in PID mode.
• Generate the mesh for the given component.
• Do the same procedure for various target lengths that they are given.
• Check the unmeshed surface
• Regenerate the mesh.

4. Surface wrapping:

• Go to mesh deck.
• select the element by right click on the mouse.
• Click on the wrap option by clicking on the left-click option with the mouse.
• Double Click on the Wrap oct tree.

Learning Outcomes:

Geometry cleans up:

• Removal of the extended surface.
• Creating a Complicated surface
• Deleting intersected surface

PID creation for a part

• Compress the unwanted PID
• Creating the New PID 2D mesh

• Creating 2D mesh
• Find the unmeshed surface and fix that.

Surface Wrapping:

• Combine different fil:s in one file
• Creating Surface wrapping

Result:

1. Surface wrapping

Fig: Surface wrapping.

Conclusion:

Thus, surface wrapping on the given model is done successfully.
