Week 2 Bevel Gear Challenge
Grid Dependency test :
- used to check mesh quality
- as mesh size increase or decreases or shape of mesh changes it may cause change result
for a small size mesh result will be more accurate than the coarse mesh.as decreasing mesh size value ,for a specific value of mesh size that can't make any more visible changes in result then result will be equal to actual value
grid dependency test for a bevel gear for 3 mesh sizes (4mm,5mm,6mm)are shown in table below:
| mesh size | 4 mm | 5mm | 6mm | |
| deformation(m) | max | .047899 | .047898 | .047898 |
| min | .025217 | .025217 | .025217 | |
| strain | max | .0017736 | .0016363 | .0018103 |
| min | 1.8473e-10 | 1.9846e-10 | 1.8951e-10 | |
| stress (Pa) | max | 2.636e+8 | 3.1425e+8 | 2.8918e+8 |
| min | 30.17 | 12.948 | 15.554 | |
Results:
- for all three value of mesh size deformation doesn't show any significant change
- but for equivalent strain there is slight changes are visible and also for equivalent stress too
4mm 5mm 6 mm
