Week 5 Challenge : Surface wrap on Automotive Assembly

AIM:

For the given models, check for the geometrical errors and delete surfaces that are unwanted for the Surface wrap as shown in the videos.

After clearing geometry, Merge all 3 models and perform surface wrap.

Target length for Wrap = 3 mm

GIVEN MODEL:

Model 1: (ENGINE)

Model-2 (Gear box)

Model-3 (Transmisson)

TOPO Cleanup Procedure:

• As we see the model given has many single cons, we want to do some Geometry checks to explore what are the errors we are encountering here,

• SINGLE CONS- the edge which is shared by only one surface.

• DOUBLE CONS- the edge which is shared by two surfaces.

• TRIPLE CONS- the edge which is shared by three surfaces.

• And the model has some overlapped surfaces which have to delete to reduce the error during the meshing process.

• We have to check the triple cons also, in which region they are needed or not.

• Delete the unwanted ring structure as shown in the below picture.

All the openings in the geometry are closed using creating a new cons option.

Steps 1 and 2 are repeated for the transmission and the gearbox geometries.

Now that the geometric errors are solved, all the 3 components are merged into a single geometry.file> merge> merge model with current model

To surface wrap the geometry go to mesh> elements> wrap> constant length. Here give the target length as 3mm for all the components as per the problem statement.

Conclusions:

Hence, the assembly of the engine, transmission, and the gearbox is surface wrapped with the target length of 3mm.
