Week 5 Challenge : Surface wrap on Automotive Assembly
Aim:
- To understand the concept of SURFACE WRAP.
Take away:
- Cleaning up the geometry.
- Using tool - MERGE.
- Using tool - SURFACE WRAP.
==============================================================================
Geometries before clean up:
1) Engine:
- There are lots of unwanted regions.
- This unwanted regions must be removed.
2) Gear Box:
- Compared to Engine it has lot less errors in the geometry.
3) Transmission:
- At the end we eill clean up the transmission.
==============================================================================
Engine Clean up:
- As seen from the above figure (engine), there are lot of unwanted regions of leat interest.
- This can be solved by setting proper view and deleting the unwanted regions by using UNIVERSAL DELETE option.
- These errors can be eliminated by setting a view and then delete.
- Best practice is to hide the needed PIDs and then select the unnecessary features.
- In this case, triple cons are not considered as an error.
- This looks much more cleaner than before.
- Still got some single cons to remove.
- These kind of overlapped surfaces must be removed.
- Care muct be taken while deleting those features.
- Once the clean up is done, try to run a geometry check. You might find few warning or penetration errors.
- As seen near the Geometry one can see exclamation mark. (!). That is warning sign.
- The one where cross appears, that is an indication of error and must be resolved.
- Finally the engine geometry looks like as shown below:
==============================================================================
Gearbox clean up:
- Pre clean up geometry of gearbox is shown below:
- Initially, run a topo check.
- Start with hiding necessary PIDs.
- This model does not have many errors.
==============================================================================
Transmission clean up:
- Geometry before clean up:
- Run a topo check.
- Start by hiding the required components by PIDs.
- Delete unnecessary features.
- After deleting, the model should look like in the figure below:
==============================================================================
Merging all the three components:
- Before performing surface wrap, we need to merge all the three components.
- Navigate to FILE and select MERGE option - select components one by one.
- After merging:
==============================================================================
Surface Wrap:
- Go to mesh deck.
- Navigate to ELEMENTS.
- Select WRAP and select CONSTANT LENGHT.
- Double click on empty.
- Click on Untitled.
- Target Length = 5 mm.
- Select Mesh in the same dialogue box.
- After clicking on OK, another box will pop up.
- Double click on CONTENTS 0.
- Select all and click on green arrow and then click on OK.
- Then Run the case.
- Mesh is shown below:
==============================================================================
Conclusion:
- Applied tools to remove unnecessary features, surfaces.
- Explored MERGE tool.
- Performed surface wrap on the entire assembly.
