Week 2 Bevel Gear Challenge
#2 Week Ansys Workbench
Grid Dependency: In terms of FEA Grid Dependency can be defined as refining of mesh until reaching the optimal results in the simulation. Atlast you will obtain a component with perfect mesh
Case-1: Grid Dependency Test on Bevel Gear with Mesh Size of 6mm.
- Import the given Bevel Gear component to the Ansys workbench.
- Edit the spaceclaim geometry and select the inner surface of the gear and create a circle and pullout the unwanted surface.
- Do it also for the small gear.
- Then update the geometry and model.
- Then edit the geometry and you can see the below image in the graphical area.
- Select the surfaces of the gear in the geometry both the contact and target body faces.
- Create the Joints and select the required parameters.
Goto the Analysis Settings and set all the parameters.
No. of time steps =6
Large Deflection = ON
Initial Time Step=0.2s
Minimum Time Step=0.1s
Maximum Time Step=1s
Insert the requirements in the analysis settings:
