Week 2 Bevel Gear Challenge

Question ;

1)Write a few words on what a grid dependency test is and its use.

2)Perform a grid dependency test for the Bevel gear simulation for mesh sizes of 6,5 and 4 mm

3) Solve for Von-Mises stress, Equivalent elastic strain and Total Deformation using the previously mentioned mesh sizes.

4) Present your findings in an organized manner.

Aim;

To conduct a grid depency test with the bevel gear considering the different mesh size

Software used :

Ansys workbench 2021 R2 .

GRID DEPENCY TEST:

Its define with conducting a simulation of same geometry and boundry condtion by varing the single parameter alone .

Based on this test we can reduce the time used to do multiple ittrations for a single model and less storage space .

This will give a clear picture for the analysis to fixed a standard to do the simulations and results will be constant because of the mesh size from this mesh size the result will be constant , So we can fix this mesh as standard mesh size for this model and do further simulations .

Procedure :

Import thr model from the skill lync portal .

Open the ansys workbench and static strutural in the project area and add the model in the space claim .

Remove the unwanted cad in the model and save it.

Go to the mechnical and mesh the model we need refinement in the faces so we are doing the face meshing to give the gear mesh a good flow .

Select the all faces and give face mesh .

For the loads give rovalute joint and select the big gear and small gear .

To assign the boundry conditions load and movement in tabular data and defive the rotation in clock and anti clock wise directions so this system will mesh and work .

For the results assign total elongation,equavalent stress and equvalent elastic strain .

Now run the simulation wait until it sloves and after it sloves go to prameteric study and assign the mesh sizes of 6 , 5 and 4 , based on this given data it will slove the previous results for the given mesh sizes and provide the result .

we can see the results in the tabular data and understand that the mesh size of given all are max in the same line .

Result:

Thus the given bevel gear is meshed and simulated in the ansys workbench .
