Week 5 Challenge : Surface wrap on Automotive Assembly

AIM:

For the given models, to check for the geometrical errors and delete surfaces which are unwanted for Surface wrap. After clearing geometry, Merge all 3 models and perform surface wrap with target length for Wrap as 3 mm

DESCRIPTION:

FOR ENGINE MODEL

Opening the model in ANSA

Deleting the unwanted surfaces

Deleting other surfaces in top view

Deleting in back view unwanted surfaces

Deleting othe surfaces

Deleting the rings

Deleting unnecessary rings

Using NOT boolean with PID selection we see the rings as follows

Now we see a clean model as follows

FOR GEAR BOX

Now loading the Gear box and deleting the unwanted surfaces

FOR TRANSMISSION MODEL

Filling the single cons

Now opening the transmission

solving triple cons for bolts

Deleting overlapping surface

Hiding all PIDs we see some unwanted cones deleting them

Now surface wrapping

Before that we need to close the open holes using new>coons/fitted as follows

Now before surface wrap we do the assembly of the components as follows

File>merge open

Merge with transmission is as follows

Now merging for gear box as follows

SURFACE WRAP

Now going to Mesh window and then Elements>wrap with constant length

giving mesh length as 3mm

Now to run the wrap

The surface wrap generated is as follows

Front view

Top view

Left view

Bottom view

Back view

Right view

Using not for the front and rear end to see the volume

we see as follows

we see the other end from the one end

This means the surface wrap is done successfully.

CONCLUSION:

Thus the Surface wrap along with eliminating geometrical errors and topo clean up has been generated successfully.

For it to get the finer surface wrap we need to reduce the mesh size which even takes lot time to generate the surface mesh and consumes time but generates a good geometrical mesh.
