Week 8 - Universal Joint
Obejective:
You 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.
Solution:
-Firstly, we need to open ANSYS workbench and drop down transient structural.
-Assign required materials in the directory.
-Now, import geometry to spaceclaim and see if there are any abnormalities.
-If there are any then fix them and open the geometry in mechanical module.
-Now, we need to assign joints to the geometry.
-Fixed Joint:
-Revolute Joint-1:
-Revolute Joint-2:
-Revolute Joint for the first 4 bolts:
-Revolute Joint for the next 4 bolts:
-Now, we need to mesh the geometry with 3mm element size.
-Now, we need to assign boundary conditions to run the simulation
-Now, we need to assign the revolute motion of rotation of 150 degrees to the simulation.
-Now, we need to give the output parameters to run the simulation.

Conclusion:
From the above table we can say that the Deformation for all the three cases is constant. But, Equivalent stress of the three cases differ where Case-1(Structural Steel)> Case-2(Strainless Steel)> Case-3(Titanium Alloy).
As young's modulus of Structural steel is higher than that of titanium alloy. Hence, stress of structural steel is higher than that of titanium alloy.
