Week 8 - Universal Joint

Objective of challenge: To perform a transient structural analysis on a double universal joint with a spring using three different materials i.e. Structural Steel, Stainless Steel and Titanium alloy, The three materials must be used on the joint with the springs alone. Find out the values of Equivalent stress and total deformation.

Simulation setup configuration as follows:

1. Model as follows

2. Part names are specified as

3. Material applied are

Case 1

Case 2

Case 3

4. Connections configured as

5. Mesh size is configured as

6. Analysis settings are configured as

Transient simulation results are as follows:

Description	Case 1 (Structural Steel)	Case 2 (Stainless Steel)	Case 3 (Titanium alloy)
Equivalent stress	Max 1639.9 Mpa	Max 1588.4 Mpa	Max 802.53 Mpa
Total deformation (Joint spring)	Max 25.575 mm	Max 25.571 mm	Max 25.562mm
Total deformation	Max 38.637 mm	Max 38.637 mm	Max 38.637 mm
Conclusion	1. Found no difference in values of Total deformation. 2. Found less equivalent stress in "Titanium alloy" compared to Structural steel and Stainless steel.
