Week 1 Spur Gear Challenge
Spur Gear Challenge
AIM
To carry out a static structural analysis on spur gear with given material.
PROCEDURE
To find and compare the results of Equivalent stress, Total deformation, Stress intensity for all the cases.
Case-1: Cast Iron
Case-2: Cast Bronze
Case-3: Cast Steel
- Case 1:
Using Cast Iron(ductile) as a material, carry out a static structural analysis to find out Equivalent stress, Total deformation and Stress intensity(Learn about what stress intensity is). Find location for possible fracture
Import the geometry.
select the material.
bronze material.
And open the model panel.
In connection panel connect the spur gear.
Each spur gear has 13 teeth.
And it has 26 faces on each spur gear.
contact size = frictional.
behaviour = symmentry.
formulation = augmented tagrange.
interface treatment = adjust to tough.
After that create joint
there are two joint
connection type = body-ground.
And select right and left side.
mesh the component with element sizing of 1mm.
Analysis the static structural in analysis setting there are 6 steps
defining by = time
Use joint load on it.
After solving the problem
- Case 2:
Using Cast Steel as material, perform the same analysis for the results as in Case 1.
Import the geometry.
select the material.
cast steel.
And open the model panel.
In connection panel connect the spur gear.
Each spur gear has 13 teeth.
And it has 26 faces on each spur gear.
contact size = frictional.
behaviour = symmentry.
formulation = augmented tagrange.
interface treatment = adjust to tough.
After that create joint
there are two joint
connection type = body-ground.
And select right and left side.
mesh the component with element sizing of 1mm.
Analysis the static structural in analysis setting there are 6 steps

- Case 3:
Using Cast Bronze as material, perform the same analysis for the results as in Case 1.
Import the geometry.
select the material.
cast iron material.
And open the model panel.
In connection panel connect the spur gear.
Each spur gear has 13 teeth.
And it has 26 faces on each spur gear.
contact size = frictional.
behaviour = symmentry.
formulation = augmented tagrange.
interface treatment = adjust to tough.
After that create joint

And select right and left side.
mesh the component with element sizing of 1mm.
Analysis the static structural in analysis setting there are 6 steps
defining by = time
Use joint load on it.
After solving the problem
Objective 2:
Write a detailed report comparing the results of the three cases and conclude which material would you recommend based on these results.
Kindly attach the simulated data in a Zipped format (.wbpz) Since it has some mark allocation for the submission under the assets block.
(P.S.
- Include screenshots of the results and compare them side by side.
- Include tables/ graphs /charts containing the results.
- Attach animations for the results)
Note: The materials can be found in Granta Design sample materials in the academic version of ANSYS.
If you don't have the materials in your library, you can create a new material with the properties mentioned below:
CAST STEEL
BRONZE
CAST IRON
RESULT
TOTAL DEFORMATION STRESS INTENSITY
CAST STEEL = 30MAX 386.15MAX 411.6MAX
CAST IRON = 30MAX 377.44MAX 401.06MAX
BRONZE = 30MAX 371.87MAX 399.06MAX
