Week 8 Worm Gear Challenge

Objective: To perform a transient structural analysis on a worm gear assembly using ANSYS Workbench.

Procedure:

1. Contacts:
2. Joints:
3. Meshing (Mesh Element Size 1 mm):
4. Boundary Condition:
5. Joint Load Time Variation:

Analysis:

1. Total Deformation:
2. Equivalent Elastic Strain:
3. Equivalent Stress:

Result:

Time Step Position	Total Deformation (mm)		Equivalent Elastic Strain (mm/mm)		Equivalent Stress (MPa)
50	Maximum	Minimum	Maximum	Minimum	Maximum	Minimum
	23.478	0.87692	0.010656	5.5299×10^-11	2041.2	3.1275×10^-6

Conclusion: For the first step, initial time step and minimum time step were both 0.1 s and maximum time step was 0.4 s. For the remaining steps, carry over time step was turned on and the minimum time step was again 0.1 s and maximum time step was 0.4 s. The worm completes 2500 degrees of rotation in 50 steps in this simulation. All the results have been tabulated only for the last step i.e., when the simulation comes to an end. The simulation went through successfully.
