Surface wrap on Automotive Assembly

Aim:

To clear geometric errors, merge and surface wrap of all three given models.

Given:

Target length = 3 mm.

Engine Model:

Gear Box Model:

Transmission Model:

Procedure:

Step:1

1. Import the CAD model into ANSA
2. Clear all the unwanted surface in the model in topo module.
3. All rings like structures are made by CAD professionals in order to create fillets or some kind of special surfaces.
4. We are consider only single cons present in outer surfaces, because while performing surface wrap inside geometric is not considered.
5. Close all the surface from outside, so that it will prevent to create dent while performing surface wrap.
6. Repeat the topological clean up for individual model.

Step 2:

1. After clearing topological errors in all models,next step is to merge into single product.
2. Open ANSA ⇒ File ⇒ Merge.
3. 
4. Select the corresponding model to be merged.
5. Engine ⇒ transmission ⇒ Gearbox.

Step: 3

1. After merging three models, go to Mesh Module.
2. 
3. In Mesh Module,under elements section click wrap.
4. 
5. Wrap ⇒ Constant length
6. 
7. Double click the status for opening it.
8. 
9. Double click the parameters options and give the suitable mesh length.
10. And then click the contents option and select appropriate PIDs to be surface wrap.
11. click Run to execute.

Result:

Surface wrap is used to perform fluid flow outside of the surface.
