Week 8 - Universal Joint

Objective: 

To perform a transient structural analysis on a double universal joint with a spring using three different materials to be used on the joint with the springs alone Structural Steel, Stainless Steel and Titanium alloy.

Tool/Software: Ansys Workbench 2022R

Producer: Follow the steps in the video

Results: 

Universal Joint_Case-1 (Structural Steel):

Equivalent Stress Maximum = 1706.455914 MPa
Total Deformation Maximum = 38.63703489 mm
Equivalent Stress 2 Maximum (Driven Yoke) = 1706.455914 MPa
Total Deformation 2 Maximum (Driven Yoke) = 23.85824003 mm

Universal Joint_Case-2 (Stainless Steel):
Equivalent Stress Maximum = 1652.101156 MPa
Total Deformation Maximum = 38.63703489 mm
Equivalent Stress 2 Maximum (Driven Yoke) = 1652.101156 MPa
Total Deformation 2 Maximum (Driven Yoke) = 23.85824381 mm

Universal Joint_Case-3 (Titanium alloy):
Equivalent Stress Maximum = 839.8564538 MPa
Total Deformation Maximum = 8.63703489 mm
Equivalent Stress 2 Maximum (Driven Yoke) = 839.8564538 MPa
Total Deformation 2 Maximum (Driven Yoke) = 23.85830741 mm

Comparison of three materials:

	Unit	(Structural Steel)	(Stainless Steel)	(Titanium alloy)
Equivalent Stress 2 Maximum (Driven Yoke)	MPa	1706.455914	1652.101156	839.8564538
Total Deformation 2 Maximum (Driven Yoke)	mm	23.85824003	23.85824381	23.85830741

Conclusion: 

The Titanium alloy is a low-stress material compared to other materials in this application.
