Week 8 - Universal Joint

UNIVERSAL JOINT CHALLENGE

OBJECTIVES

In this challenge, you will have to perform a transient structural analysis on a double universal joint with a spring using three different materials: Structural Steel, Stainless Steel and Titanium alloy(They can all be found in the General Materials section) The three materials must be used on the joint with the springs alone. Use a refined mesh if possible, for the academic license. You need to obtain the Equivalent stress and total deformation for all the three cases and compare them and submit a report regarding the same.

PROCEDURE

• First, we have to input the engineering materials with required properties or else by creating with required properties.

• Then we have to import our model into ansys, import the model and open it in space claim so that ansys will read it.

• Then assign required connections in this assignment we will use Body to Ground Revolute contact between the components spring and Gear and Body to Body Revolute contact between the Pin connections.

• Then mesh the component with required mesh size in this assignment we will use
  • Mesh – 4mm
  • Nodes – 15076
  • Elements – 7349

• Analysis setting then assign revolute joint load.

• Then give the required solution parameters then solve.

RESULTS

Case1 – Structural Steel

Total Deformation

Equivalent stress

Equivalent Elastic strain

Equivalent stress of Spring body

Case2 – Stainless Steel

Total Deformation

Equivalent stress

Equivalent Elastic strain

Equivalent stress of Spring body

Case3 – Titanium Steel

Total Deformation

Equivalent stress

Equivalent Elastic strain

Equivalent stress of Spring body

Conclusion

	Total Deformation (mm)	Equivalent Stress (MPa)
Structural Steel	38.637	1972.7
Stainless Steel	38.637	1910.5
Titanium	38.637	969.62

From the above stimulation result is the total deformation is equal in all the cases while in the stress is low in Titanium alloy material than other materials because the Young's Modulus in titanium is low compared to other materials.
