Week 8 - Universal Joint
Week 8 - Universal Joint
AIM
To run the Transient structural analysis for Mechanism 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.
