Introduction
Analysis will be done on a fixture designed for ME 462: Capstone Design
Project sponsor is Remy, Inc
Out of Anderson, IN
The analysis will be purely structural
Von Mises stresses
Deflection/Deformation
Background
Most analysis of products is done using FEA
Testing is usually a “break it” test
Tests aren’t universal and standardized
No reliable way to compare current products to competitor products
The particular fixture being tested will be used to connect the drive shaft to the torsion machine
The pin end will be held by the fixture
Analysis and Results
This method would not provide any moment at all
There is no implementation in Workbench to apply a pressure on part of a surface
An okay approximation, but not quite accurate
Placement of point forces based solely on clicking the mouse
This discrepancy caused forces to be unbalanced
Conclusions
Design was approved through FEA using a combination of Pro E and ANSYS Workbench
Good example of the importance of learning the theory behind FEA.
