Week 2 Bevel Gear Challenge

Grid Dependency Test :

Grid Dependency Test is a test in which, the analysis begins with Coarse mesh and it is then refined to finer mesh, in order to acheive more accurate result with more finer mesh .

Case 1 : Mesh Size 6mm

Model(Common in Case 1,2 & 3):

Material(Common in Case 1,2 & 3):

Contact(Common in Case 1,2 & 3):

Mesh:

Face Meshing (Common in Case 1,2 & 3):

Boundary Condition(Common in Case 1,2 & 3):

Analyis Setting (Common in Case 1,2 & 3):

Solution :

A) Von-Mises Stress:

B) Equivalent Elastic Strain:

C) Total Deformation:

Case 2 : Mesh Size 5mm

Mesh:

Solution :

A) Von-Mises Stress:

B) Equivalent Elastic Strain:

C) Total Deformation:

Case 3 : Mesh Size 4mm

Mesh:

Solution :

A) Von-Mises Stress:

B) Equivalent Elastic Strain:

C) Total Deformation:

Conclusion :

Element Size	Von-Mises Stress(MPa)	Elastic Strain	Total deformation(mm)
6	104.55	0.00061769	47.893
5	124.46	0.00077212	47.893
4	136.92	0.00073072	47.893

From the above data we can see that the by decreasing the element size ,stress & strain both increased, this is due to because in increasing no. of elements.

Element size 5 & 4 will have comparable results .If we further reduce the MEsh size , the result might increase but that increases the run time as no. of element increases.
