Week 8 - Universal Joint
Universal Joint
AIM
To run the analysis for Universal Joint on a total of 3 different cases with change in material terms and provide the inference on the output.
Objective
To find and compare the results of Equivalent stress, directional deformation, Equivalent elastic strain, and contact pressure in all cases.
For 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. Submit a report regarding the same.
CASE 1:Structural Steel

CASE 3:Titanium alloy
CASE 1:
Structural Steel
Import the model.

select the material.
Structural steel.

And open the model panel.
In connection panel connect
And delete the contact component
And create the joint
create the fixed joint

2nd revolute joint
ground to body

3rd revolute joint
body to ground

revolute joint
body to body to all 8 joint

Mesh the component with mesh option.

mesh the component with element size of 2mm.
Analysis setting
step = 5
with large deflection = ON
weak spring = program control
Auto time step = ON
Output control = ON

Create the joint rotation

CASE 2
Stainless Steel
