Week 5 Challenge : Surface wrap on Automotive Assembly

AIM :

To check for the geometrical errors and delete surfaces which are unwanted for surface wrap and to Merge all 3 models and perform surface wrap.

Target length for Wrap = 3 mm

Objectives -

• Perform geometrical errors
• Delete unwanted surfaces
• Perform surface wrapping.

Procedure:

Engine Model:

• Open ANSA and import parts seperately to cleanup the geometry.

• Delete the unwanted surfaces and overlapping surfaces from the engine.
• Delete unwanted circle type structures from the Engine.

• Now using NOT PID we can hide the main parts of Engines .
• This is how it looks after hiding the mains.

• After cleaning up the Engine

Transmission Model:

• Import the transmission model into the ANSA and perform the TOPO cleanup
• Delete the unwanted and overlapping surfaces

Gear Box:

• Import the gear box into the ANSA and cleanup the unwanted and overlapping surfaces to avoid the errors.

MERGING :

• Go to file and select the merge option and select the parts that are to be merged.

• We should get 0 errors after merging the parts

• After merging all the parts

• Fill the holes with the new faces option for proper surface mesh.

Meshing:

• For meshing we will go to elements n then click on wrap
• Double click on the status to change the status of the wrap

• Select the contents that are to be wrapped and compress unwanted PIDS

• Now click on RUN to run the wrap process
• After that the status is changed to ready then the model is wrapped

• Model is shown below

Results:

• Learning outcomes from this challenge -

1. Geometry cleanup
2. merge models
3. surface wrapping
