Advanced Structural Analysis using ANSYS Workbench-Worm Gear Challenge

Introduction

The purpose of this challenge is to perform a transient structural analysis on a worm gear assembly. For this challenge,we rotate the worm so as to get to almost end of the half cut and get results for Equivalent stress, Equivalent elastic strain and the total deformation in the model.

Procedure

Import the geometry and open it in space claim

For people using academic versions,the best choice is to use the split option and click on the ring(Base of the teeth).This splits the ring and all the tooth into different components. Click on the saw icon and remove half the teeth.

Click on combine and click on the ring and all the teeth leftover. To combine all the tooth and the ring back into one component.

Open the mechanical module

Setup all the contacts. Setup the revolute joints.

I am using a 2mm mesh.

I am using 30 time steps and 1500 degrees of rotation.

Results

Stress

Total Deformation

Strain

Conclusion

The simulation ran as expected and no unexpected errors where created.
