Week 8 Worm Gear Challenge

Objective: To perform simulation of worm gear and find out Equivalent stress, strain and total defromation

Setting up analysis: The geometry is imported and opened in ANSYS mechanical. The names of the parts are renamed and the contacts are updated based on definition.

More faces for contact on target body are selected, about quarter of the gear.

Added two body to ground revolute joints for worm and gear.

Mesh: The mesh smoothing option is selected as 'high' and mesh size is taken as 10mm

Analysis settings:

For the first step

Rest of the steps

Boundary conditions: A joint load is selected for body to ground worm and tabular data is used

Solution:

Total deformation

Equivalent stress

Equivalent strain

Results

Deformation(mm)	Equivalent stress(Mpa)	Equivalent strain
7.2	865	0.005

Conclusion

The simulation is perfomed and run properly.
