Pre-Analysis & Start-Up

Pre-Analysis

In the Pre-Analysis step, we'll review the following:

• Mathematical model: (e.g.: We'll look at the governing equations + boundary conditions and the assumptions contained within the mathematical model.)
• Numerical solution procedure in ANSYS: (e.g.: We'll briefly overview the solution strategy used by ANSYS and contrast it to the hand calculation approach.)
• Hand-calculations of expected results: (e.g.: We'll use an analytical solution of the mathematical model to predict the expected stress field from ANSYS. We'll pay close attention to additional assumptions that have to be made in order to obtain an analytical solution.)

Numerical Solution Procedure in ANSYS

Hand-Calculations of Expected Results

The results can be approximated using beam theory as shown in this document. Note that the document uses a different bike crank so while the process is the same, you would expect to find different results. 

Start-Up

This tutorial assumes that you have completed the bike crank tutorial. The ANSYS project file generated from the bike crank tutorial is used as a starting point for this tutorial.
