Week 8 - Universal Joint

Objective: To perform a transient structural analysis on a double universal joint with a spring using:

1. Case 1: Structural Steel for the joint with the spring.
2. Case 2: Stainless Steel for the joint with the spring.
3. Case 3: Titanium Alloy for the joint with the spring.

Procedure:

1. Joints (1 To 5):
2. Joints (6 To 10):
3. Joints (11):
4. Meshing (2 mm):
5. Boundary Conditions:

Analysis:

1. Case 1:
   1. Total Deformation:
   2. Equivalent Stress:
2. Case 2:
   1. Total Deformation:
   2. Equivalent Stress:
3. Case 3:
   1. Total Deformation:
   2. Equivalent Stress:

Result:

Cases	Total Deformation (mm)		Equivalent Stress (MPa)
	Maximum	Minimum	Maximum	Minimum
Case 1	38.637	0	1473.3	9.3756×10^-6
Case 2	38.637	0	1428.6	9.022×10^-6
Case 3	38.637	0	729.67	4.7703×10^-6

Conclusion: The total deformation remains the same in all the cases implying that it is independent of material properties. The equivalent stress is greatest in case 1, lesser in case 2 and least in case 3. It depends on material properties of the components.
