MESHING THE CRANK HOUSING CHASSIS AND HUB IN 3D USING TETRA ELEMENTS

OBJECTIVE :

• Import the given models to the hypermesh software
• Clean the geomentry for given models manually using quick edits, defature.
• Mesh the given models in 2d with tera elemnts.
• After 2d meshing go to 3d mesh and mesh the given models.
• Check the tetra collapse elements and fix the failed elements.

PROCEDURE :

1. Import the given model into the hyper mesh software, here I am importing the housing model and see the geometry clearly.
2. Here there two parts in one model so organise the parts and go for the geometry clean up.
3. Now clean up the geometry manually using quick edits and defeature the surafce fillets.
4. Defeature th fillets with help of surface fillet option
5. Check the surfaces whether it has any surfaces which is more than given maximum element size.
6. If any surfaces has more than maximum element size try to remove the surface using replace points and also use toogle option.
7. Now set the given criteria in criteria table it is useful when checking the quality of elements.
8. Now go to the 2d mesh and select the trias and give the elemnt size of 5mm and mesh the model.
9. Now check for any failed elements and fix the elements using quality index>> clean up option or remesh the failed elemnts using mask option.
10. After complete 2d mesh go for the 3d tetra mesh ad select the component and mesh the given model.
11. Now 3d tetra mesh is completed and check the tetra collapse in tool >> check elements option.
12. If tetra collapse shows zero percent then there is no failed elements.

Here I am following the same procedure for remaining models.

• This is Chassis model and I have done above procedure for this model.

• This is the crank housing model and I have done same procedure for this model.

RESULTS :

Thus 3D meshing is completed for given models and tet collapse is checked using the hyper mesh software.
